Gr oup 4 : Downgrade at 3 year intervals Declassified after 12 years PREFACE This preliminary transcript was made from voice tape recordings of the GT-5 flight crew debriefing conducted August 30, 1965 thru September 1, 1965 at the Crew Quarters, Cape Kennedy , Florida. Although all the material contained in this transcript has been edited, the urgent need for the preliminary transcript by mission analysis personnel precluded a thorough editorial review prior to its publication. Errors in this transcript will be corrected as soon as possible and an official transcript will be published at a later date . This document contains a transcript of the first part of the debriefing, during which the crew described the mission generally from an operational viewpoint . A preliminary transcript of the re­ mainder of the debriefing will be published by September 3, 1965. It will cover systems operations , operational checks, visual sightings, experiments , pre-mission planning, mission control , and training. a i eJ~FIDff:!TIAL 9'0Ni;10 ENTll(t ~ TABLE OF CONTENTS Page Number Paragraph 1.0 COUNTDOWN 1.1 Crew Insertion. 1.2 Communications . 1. 3 Crew Participation and Countdown . 1.4 Comfort . 1.5 Environmental Control System 1.6 Sounds 1.7 Vibrations 1.8 Visual 1. 9 Crew Station Controls and Displays . .. .. . .. .. .. .. .. . . ........ . .. ........... ........... 2. 0 POWER.ED FLIGHT 2.1 Lift- Off Cues 2. 2 Roll Pr ogram 2.3 Pitch Program 2 . 4 Aerodyna.mci.cs. 2 . 5 Environmental Control System . 2 . 6 Maximum q 2 . 7 Windshear 2. 8 DCS Update . 2. 9 Engine 1 Operati on. 2. 10 POGO. 2 . 11 Engine 2 Status 2 . 12 Acceleration g ' s 2 ,13 BEXJO 2 . 14 Staging 2 . 15 Engine 2 Ignition 2. 16 RGS Initia t~ 2. 17 Fairing Jettison 2,18 GO/ NO GO 2, 19 Systems Sta tus 2 . 20 SECO 2. 21 Steeri11g , ,1 . .1 .1 .1 .2 2 .... .... 2 3 4 .... . . ...... .. . . ..... . .. . . .... . ... .. . .. . .... .... 6 7 8 8 9 .... .... .... .. . . . 9 9 9 9 10 12 12 12 13 13 ~4 15 20 21 21 22 I' ...... 3.0 4.0 INSERTION 3. 1 Post- SEXJO 3. 2 SEXJO + 20 Seconds 3.3 Inser tion Activities ..... ....... . . .. . . . . . 23 26 30 38 ORBITAL FLIGHT Wf.lE>ENTl~E 5.0 RETROFIRE 5. 1 !R- 36 Events . . 256 Events . 5. 2 ~ - 1 Events . . . . 5.3 5 ,4 1R- O Events . . . . 5.5 Retropack Jettison . 5 . 6 Communications . ~R- 6 .0 7. 0 REENTRY 6.1 . . . . . . . 400 K 6 . 2 Acceleration profile .

Conrad Yes , we had the suiting thing down on my cuffs and everything so that we got right ou t t here and, boy, th& Gunter was ready for us and i n we went . Cooper They were all set . There were no delays and every­ thing went exceedingly well on t he gantry. 1 . 2 Communications Cooper Communications , I thought were good and no probl em at all on communications, and everything went real well. Conrad Yes , Stoney handled that whole thing real well . Cooper All right, volume was still down on the little comm sets in the transfer van there . That ' s Stoney' s little improvement . 1 . 3 Crew Participation in Countdown Cooper Crew participation in the countdown was good . I didn ' t see anything at all wrong. Conrad Yes , we weren ' t rushed . We felt t hat we had enough time to get the switches in the right position and just ever ything went real good. 1.4 Comfort Cooper Comfort was real fine . We went on to two suit fans 2 right away. I thought we felt plenty cool the whole time. Cooper ECS was good. Never any problem with it . 1.6 Sounds Cooper Sounds , I thought the only sounds tha·; we had that were abnormal we'd been warned about. When the prevalves opened, they were fairly loud and when the engines gimballed they were quite loud , and both of those we were aware of the fact that they would cause a lot of noise and vibrat:.on. Conrad There is something that really dings t he booster too when they start .. . . I don ' t--whet her they drop a platform away. Cooper It ' s before they start moving the gant ry. Conrad Just before they start lowering that erector. Boy, something really, like it really bangs tha t booster , I thought. I still don't know what it is , but , of course, we ' d been up there with the erector down twice before that so we were sort of e~tting used to those kind of sounds. 1. 7 Vibration Cooper Okay , vibrations we already covered tr.at . vibrations. Sounds , 3 ,. 1.8 Visual Cooper Visual . Nothing.... Conrad Oh , yes , wait a minute, I started getting this win­ dow fogging . Cooper Well, let ' s cover that under the right area . Conrad Well, it was actually in the countdown when the erector went down before liftoff . Cooper Well , okay , allright . Conrad I mean we still had it later . Cooper Well, you want to cover that now then in systems . Conrad Well, is that what this means , is visual, or does that just mean something else? FCSD REP Yes, that ' s before liftoff. Conrad Yes , well t lri,s-tra-,:5pened 6e:f'1 Cooper / Powered flight is next . Allright , even before liftoff , really is completely unforgiveable. was filthy. hat this Each window Just fogged completely over, and it was on the inside of the outer pane of glass . It was I within the sealed unit of glass , and it was so foggy when they lowered the erector that it it was frozen over solid, I d neither could Conrad Well, it had fogged over before they lowered the (j()tqflDENTIA[ ,. 4 erector and then the guys heated it w:.th hot air to make it go away and that just made th:.ngs wor se when they lowered the erector . Cooper It didn't make it go away all the way. Conrad That I s right it made'"it- ~ actually. Cooper / L my side in my window ~etweer. the inside pane and the two outside panes of\\8-~s , I had a sma ll bee , and I had a fly, and I had\several flecks of things that I had written u~ before and never got corrected, and they were the whole flight, and I ' m sure they will show up on all the films and everything. Now between the outer sealed panes of glass there were numerous little specks and of stuff and throughout the flight as . .. well , we ' ll cover that later, but that was even 7rore the flight started . The windows were not pla/n a nd were not in good shape to go forthe--f~. 1 . 9 Crew Station Contr ols and Displa_ys Conrad I think the Gemini cockpit is a pretty good cockpit . Cooper I think in general that crew stations eontrols and displays were pretty adequate . Conrad I 've got a couple comments on switches and things, but these are . . . . ~FIDENTIAL - 5 FCSD REP Okay , how about the time you spent in there on prelaunch . Cooper Do you think that this is about right? Yes , yes , I think that this is just about right . I think that if you cut it down too much more than that you are going to be ....you could cut it down some more , there's no doubt . .. . Conrad It ' s that cabin purge cycles when you ' re not doing anything really , and that ' s excellent time . Cooper ... that you can cut it down, but that ' s the thing that takes the time for both the ground crews ... and that ' s lost time. Conrad I don ' t know . ... I don ' t think you want to rush the crew and now our count that second day went by the clock, boy. We got in there at the right time . We counted down and lifted off on, and I didn ' t feel that I was rushed , and I didn ' t feel that I sat in there for an excessive amount of time . Cooper No , I didn ' t either. I thought that it went just about right , time wise . ,. Conrad Long as there ' s no holds in the count everything' s great . FtE>ENTI L 6 2.0 2.1 POWERED FLIGHT Lif t Off Cues Cooper Okay , lift- off cues , CAP COM . into the act until later . CAP CO~ didn ' t come Stoney counted us down thru ignition and lift-off and then CAP COM picked us up at l ift- off . Motion is an excellent clue . There ' s doubt in your mind when you ljft- off . You know, the second you lift- off that yot .' ve lifted . Vibration was very low. Conrad It had dropped out almost completely a.t lift- off, felt that shaking was very l i ght. Cooper There was very little vibrati on at all . vibration , very l ow. Okay, Noise I thought, was quite low . Conrad I was particularl y aware of the noises of goi ng through the max Q regionar y thing . Oh , t his is lift-off again . I thought the noises were very well at l iftoff . You know the engines were running from the outside before , you know, and man they really make a racket , but from where you are it's pretty quite . You know there running. You can here them , there's no doubt about that , but .. . Cooper Okay , on visual I don ' t . . . . day . ~ We had a very cl ear There weren't even any clouds in sight on IDENTI~ C.(&)Hft0ENTI:,\~~ au, 7 !to our sight as we were lifting off, and I couldn't tell any visual cues to lift- off, could you? Conrad You had the feeling that you were moving visually. After you get your ro ll program you see it visually and you can see the pitch program starting visually, but just at first l ift-off you don't really have any visual cues . Cockpit displays are just l ike advertised . The two stage - one lights go out, and . .. just l ike the simulator. 2 . 2 Roll Program Conrad Yes , I watched roll program on the gyro, I was watching for it to come i n on time and in glancing up when the roll program started I was still looking at nothing but blue sky, but I was aware visually as you say that the booster was rolling. Yes , you can have a airplane when you are looking at nothing but blue sky and start a motion and you may not know exactly what the motion is, but you know t hat you are moving. Cooper Now on this cockpit display, something that I got two different answers to from different people on how the gyro and the actual case was going to be set and it suddenly dawned on me that they actually set the gyro so that you are launching down the 90 degrees. You're 8 progressi ng down to 90 degrees line , e. la the simulator, although the booster sets on 85 degrees and when you turn to 72 degrees launch azimuth you are rolling clockwise so far as tr.e crew is concerned . Conrad You roll to zero . Cooper But you are rolling to is real ly to O on the gyro as precessed around so that you are net really setting on the actual launch azimuth, you are actually setting so that when you stai§'e on over i n yaw then pitch over then in your yaw your on the in­ plane line. FCSD REP You ' re coming down the zero line . Y01.:. 1 re yawing down the zero l i ne . Cooper That 's right , and I kept getting diffe.rent answers on this and this is in fact the case. Roll program was exactly right on time and ended e>:actly on time. 2 . 3 Pitch Program Cooper 2. 4 Pitch program started exactly on time. Aerodynamic Cooper Aerodynamic was nothing new or differE:nt about it . It was just standard. We build up to the noises at max Q; the noise built up to gradual level and the vibration and quantity built up to ma>:~ and then dropped off very rapidly J.1'd:i!Jitely thereafter. FlDENTIAL CONFICtleNTIA~ • 2. 5 9 ECS Conrad Right on the button. Cooper ECS was right on the money , no problem at all . Max Q we ' ve already stated . Conr ad The cabin s ealed a little bit high like they said it would . I forget the number. It was about 5.8. Cooper About 5.8 or 9 and just gradually dwindled back down . Conrad And just after we got in there by the time I looked at it again after insertion everything it bled down on our gage to 4.9, our gage read a little low . I think the actual reading , you will pr obably find the cabin actually was 5.1 1 but the whole rest of t he flight the gage never budged off the 4.9. Cooper The gage stayed right there like it was glued . 2 . 7 Wind Shear Cooper The wind shear , we had none and , certainly nothing that we could tell , but as I understand we ' ve been told that for that day anyway we had almost negible wind shear. 2 . 8 DCS Updates Cooper DCS updates were right on time . FCSD REP You had two updates? Conrad 1 plus 45 , 2 plus 25 . 2 , 9 Engine 1 Operat i on Cooper The engine 1 operation couldn ' t have been better, ----~~K)ENTIAL .. 10 It was beautiful. Just now in between engine 1 operation and engine 2 here we have t wo items we will insert in here . 2, 10 POGO One was POGO.. Cooper At 2 mi nutes and 5 seconds we started picking up POGO and I got a fairly gcod amount of POGO on through , stopping just at abcut 5 to 7 seconds before staging. POGO dropped. cl ean out exactly the same time there that we programmed POGO on the early days. Yes, that one surprised me . Conrad We ' d he1:.rd and read tbat both John 8{!.d Gus ' s and Jim and Ed ' s f l i ght that they were hardly even aware of IDGO and boy when it came in on us it was loud anc. clear and , ------- well Gordon , neither one of us could talk hardly; ( we were really vibrating with it and I was hard pressed to read the displays. By golly , if I had to re ad __:-t-;-:h;--e- -num;-er --:b- _ on __ _ , e ·a:-i~-s p~r-ays ___ I.,,. think I woul d have been hard pressed to do it, because we really had it pretty good. Cooper Yes , the rate ... the amplitude of them were such . . . 11 cps frequency and the ampl itude of them was such that you were on -- you were on the marginal 11 edge of reading of any large gage and any fine reading that you had to read, you would never be able to read any numbers. It was exactly like the POGO we did all along on the program up at Ames and as the exact amplitude , I don ' t lmow, but i t was , . . . . . It was no I think we don ' t want that ~ POGO. par icu ar y upsetting to me , because I really was fai rly familiar with POGO having been through a ll that POGO program, but this thing kind of t i ckled me that we got it to see that we had still hadn ' t solved it , but I don ' t think . . . its something you don ' t want because if you had ot~er things going wrong during that period of t i me it would make it vecy difficult to say what you had wrong or what Conrad It didn ' t upset me , but it surprised me , you lmow, because I just wasn't expecting POGO. RCSD REP Wbat g- level would you estimate it to be? Cooper Well , we were sneaking right up there . FCSD REP I mean the POGO . Cooper Oh, it was right at about 5 g ' s . FCSD REP Well , I mean plus or minus amplitude . Cooper Well I , my estimate on it was that it was something ·\ 1• 12 on the order of maybe three quarters of a g . Well, I don I t !mow whether it was that high c,r not . Conrad I thought it was at least a half , if not better . Apparently it wasn't that high . surprised. Like I say, we were really getting the -- ramrod out of it. Cooper I ws.s really s beyond what we selected as we th~ht should be the cutoff. It was more tr.an wh~ we l had selected at Ames as being max acc 7. in this.I passed up ver b • there one of the first things that happened immediately about the time that we got the pitch program was the IGS Stage 2 fuel needle failed in thE full -max deflection position. And it came back on and was reading after staging briefly and thEn failed again during staging. It was intermittent . 2 . 11 Engine 2 Status Cooper Engine 2 status stayed ... was perfect . There was not anything wrong at al l. 2 .12 Acceleration G' s Cooper Acceleration g ' s were right on the piofile , were certainly very pleasant. 2 . 13 BECO Nothing wrong at all with them. 13 Cooper . 2 . 14 BECO was right on the money . Staging Conrad Boy, that staging was smooth too . Cooper They told us that BECO was going to occur early , but it was Conrad We did loft a little bit apparently like they said we woul d because, right a fter staging .... 2. 15 Engine 2 I gnition Conrad Well , Engine 2 ignition, I wasn't even hardly aware of that other than we jus t started to get a little , yc,11 know, we just sort of went off the peg at 6 g's and Gordo said s t aging OK and Engine 2 is good and I wasn ' t even aware that Engine 2 had lit . You can ' t hear it, to speak of, but you can feel the acceleration slowly building up . FCSD REP Did you see anything visually? Conrad No , I didn't see anything. I heard the other guys talking about s ee the flash at the brig. Never saw a thing and I wasn't aware of any flash out there either . I\ Cooper J didn ' t see anything at all at BEDO. The best clue that I have on my side , is that I see the Fuel and Oxidizer needles start coming down as the engine • 14 starts burning. And then they coming c.own fairly rapidly at first, I mean you get a very definite motion on them right at first there and. they kind of settled out. 2.16 Engine 2 ignition we've already covered. RGS Initiate Cooper RGS initiate right on the money. Conrad I was going to mention that we had l of t ed and that we were expected to pitch down a.nd we did when it picked up RGS. Cooper It smoothed in very smooth, and the fading was just right. Conrad The IGS needle really deflected and I ~as , you know, I don't think it pitched, it didn't peg- out , but it did make a large dip and then when the booster came down just pitched down very smoottly down to about 75 or 80 degrees, I guess it pitched down almost 10 degrees. FCSD REP What rate did it pitch over? Conrad Very slow, but steady, at just Cooper It took about 20 seconds I guess to fade it in there . Conrad The needle came in and made a big deflection and right after that the booster started pitching and the needle started back and boy the needl e was • CQ~ElDEhJIJA 15 back and thing was right on the money at about 80 degrees. It was a very smooth transition and then do you remember they were telling, us to look for this one cps oscillation? Well, I didn't have rate needl e s like Gordo did, but I wasn't aware of any oscil lations at any time. That booster was in pitch and yaw as far as that went Cooper Those rate needles were like they were glued . There was never through boost or second stage was there ever any rate except that one tiny little rate , one teensy little rate just at when we were in POGO we got one tiny little longitudinal rate, ' just one tiny little fleck on a rate, and was the only one . Otherwise it was just smooth as silk, the whole time, rate wi se . 2.17 Fairing Jettison Cooper Fairing jettison. We jettisoned fairings at 3:25 and man do they ever go . Conrad I counted Gordo down to them. Okay, yes, that ' s a good point . Cooper Beside the scanner fairing and the nose fairing go and when the nose fairing went it went with all kinds of debris . There were pieces flying all 16 over. Conrad Yes , and I don't think it went right . I don't believe it went right , because the Rand R can was ripped up in the front , and I can show you on my side the nose went like that and there was some tape or fiber glass that goes around t he . . .. It was fiberglass cloth and it was a ll broken loose in jagged flaps sticking up t hat, you lmow, had broken loose from a long in here when i.hat cover went I had decided impression that the cover went off askew, that it didn 't jettison t he: way i t should have. And this could be a good point of putting it back to a fter insertion. Cooper Well, it ' s supposed to go off askew. Conrad Yes , well, it just di dn ' t go off clean . That 's why this was ripped up, see . Cooper Well , it something somebody might look into , but you don ' t want to recommend that they put back to after insertion , because your taking a weight penalty to carry that all the way up. Conrad Yes, I realize that , but . . . . Cooper It was designed to go off ... . Conrad That was the reason in the first place that they WIDE 17 moved it up there anyhow, because they weren't .... Cooper No , the reason they moved it up there was because they didn ' t have strong enough propulsion on those squibs and spring combinations or whatever they use . We never did get a reading on that, but whatever the total propulsive expulsion system wasn't kick­ ing, the scanner fairing wide enough but what they would come back into the booster. But didn't you have the distinct impression that the nose fairing broke into j illions of pieces when it blast . Conrad I certainly, I certainly , yes . That ' s why wh~n I say askew , I mean something didn't look right. I can't put my finger on it, but -Cooper It came off in many pieces anyway. There were many, many pieces and the whole area was just filled with debris . Conrad Yes, and then , I 'm not sure that that's when we got all that gl op on our windshiel d, the spots ... Cooper Well, I noted exactly at that time immediately after the fairing went, I noted about 5 or 6 , I saw them hit , 5 or 6 gray splots, just small ones , very small little gray- type splots and I was distinctly looking for that and watching for it and 18 they were not there before they were t'nere and I ; saw them when they hit. They h it duri:'.l.g all this debris flying around period . Conr ad I think that you can s ti11 f i nd them o:'.l. the windshields . Cooper They didn ' t burn off during reentry. But they ' re not bad and there are just a few little scattered ones and I think it might be interesting t o compare how many you get there vers us and how many you get when you jettison them in orbit . It may wel l be that jettisoni ng in orbit would be pre­ ferab l e , but I didn ' t f i nd anything objectionable t o jettisoning where they went , they wenm fine. It did add a lot of debris and I agree with Pete there was a big torn something or other out there which may just be a fiberglass thing that is kind of . .. ,. Conrad Yes , I want to get down and look at the R and R and and I can tell you what it was , describe it a lot better. We ' ll probably have some pictures of it too in the camera somewhere. I know it ' ll show up in some film . FCSD REP How l ong was this visible? bunch of stuff out there . ONFIDENTIAL You say there was a big 19 Cooper There ' s a whole fly . Oh, you mean the debris . It was gone . Conrad It was gone like that, but it just looked like the whole darn thing exploded. Cooper It looked like it just flew into a jillion pieces. It was all around you for maybe a period of a second or two . Conrad I didn't think it was that much , i t was just gone . Cooper But it was a defininite period of time when you were aware of all this debris all over and then clear . Okay, enough for fairing jettison. 20 2 . l8 GO/NO GO Cooper GO/NO GO: We never got a GO/NO GO beeause we lost our number 1 radio in about 4 minutes s ometime just prior . . . let see we got a . 8 . . . . over VR of . 8 . Wti got a V We got a GO/NO GO of , .. FCSD REP You did get a , 8? Cooper We got a .8 . Conrad Yes , that comes much later - that com(!S after the GO/NO GO. Cooper Yes, that ' s right , okay, well I don ' t remember ever getting a ... yea , we did, we go·~ MCC GO. Right we got a GO/NO GO , okay, but then immediately after . 8 we never got any·':hing at all from there on until aft er we were insi~rted and gone to UHF No . 2. Conrad I think it must be in the antenna problem, I really do . Cooper Well , there 's some problem there because the same thing happened on one of the previous flights and we definitely and completely lost radio and I swi tched over just before we inserted, I switched over to number 2 and then when I call1~d but the IVI's we were back with them then . 21 2. 19 Systems Status Cooper System Status everything .. . . Conrad We did have ... lights . Let me describe the delta P Shortly after liftoff I got the number 1 fuel cell delta Plight and I reported i t and just about t he time I reported it , then the number 2 fuel cell delta Plight came on . They s tayed on all the way through boost and they were on aft er insertion for ten , fifteen seconds and after that \ they went right back out again and that) i s it . It didn't effect anything on the fue y e11 operation, tn currents , the voltages , / t h i n g stayed fine other than • bein n----tliere was no other way of telling the~ was out of tolerance so I don ' t think it is a problem. Cooper We expected it. I ' m glad that we had them changed to orange rather than red . Conrad Yeah, yeah . Cooper Systems status in addition to that I don ' t think we had any systems that were exactly right , except the radio and the acceleration as we had expected it . We were right on the profile. 2. 20 SECO !Oa!IIAL SECO was ... 22 Conrad I think we burned out at, Gordo, 7 anc. 1/4 g's. Cooper Right. SECO was exactly on time, just exactly on time and IVI's read 002 AFT. 2. 21 Almost ierfect. Steering Cooper Steering was ... there was no steerine· accelerations or velocities that we could tell. Steering was just smooth as silk , apparently they :t.ad us going right down the slot . And when we came off, apparently we were lined up well because there weren ' t any rates because when we came off and wajted our 20 seconds there were no rates whatsoever and it was just setting there just . . . . as smootr.. as Conrad As stable as a rock . Cooper As smooth as silk so that and when we started thrusting and separating we came off :ust right straight forward . or anything. Conrad No deviation , no skidding around Just right straight off, I thought the IVI's were plus 2 . written down here. That ' s what I haVle Plus 28 right , 3 t.p. Cooper I guess that's what it was. FCSD REP This velocity you read? Conrad I was going to cover that in your ... , Cooper Your right, plus 2, it was -- that's :r·ight . Plus ~IE>l!NTtAE 23 002 . 3 ,1 Conrad I have al l the computer readouts . Cooper 008 right and how many up? Conrad 3 up . Post SECO Cooper MANEUVER CONTROLLER worked fine . We went right through .... Conrad Wel l, l et ' s go through t hat. The way we had practice SECO, Gordo, got SECO and Gordo unstowed the CONTROLLER and I armed the BUS ARM Swit ch so that we get the MSC- 1 doors OFF. Cooper Brought the propulsion power ON. Conrad Brought the ATTITUDE CONTROL Elect ric Power ON. Went from RATE COMMAND to DIRECT. switch and hit the computer. Armed the Armed t he sep spacecraft thing and Gordo and I counted the seconds down . I n the meantime , I punched off address 72 so that it was reading and then in 20 seconds we had SEP s/c . ... Cooper In 20 seconds I start ed and I called it out and started thrusting and Pete would hit the sep spacecraft ... . Conrad The reason we did that was so that we would have the inertial velocity readout on the ga.ge and that was ·beautiful 25,808 and nominal was S-.lpposed to be 25,807. You can't ask for a better calculation from a computer than that, and a lot of people don ' t have much faith in that thing but, I think that I'll bet that the computed MCC figure isn't more than a foot or two off. I t couldn ' t be because everything was nominal for hours and hours in the past, Day's it went that way where we stayed on the flight plan to the minute, to the second so I know that it was a good computation, and I have the five address readouts that we read , We read out address 72 as 25,808; address 94 which was R dot for gamma was plus 20 feet which is pretty darn small so we must have almos t a zero gamma address 97 which is the forward IVI was plus 2 feet; address 52 was perfect , it was zero. So there was no adjustment needed and if there had been an adjustment needed that would ha:ve come at 3 , 042 seconds on the computer if tbere had been an address . 52 correction and nominal 3,008 seconds so the computer computed the nomi nal thing off only by less than a minute, about a half a 25 minute of what the actual nominal value /een , s o I think thats pretty darn good ascent routine in that comput er, and I think hat ( now that we have Math flow 6 in there t his i why I think the guy shouldn't get so darn worried in MCC underspeeds and giving them burn co/rections t his Mickey Movse. I' ve been t rying to make tbis pein-t-ewe· since we got associat ed with . . . . Cooper I think we had better immediate data avail abl e on board than people have been giving it credit for . Conrad Tha t ' s right , and it really pleased me to see it come out on the computer this way. Cooper And had we never gotten our communications back we would have known tha t we were i n good shape because of the data we had on board, we didn ' t have to worry about the ground readouts and what to do ; we would have known what to do whether we had been under or over or anything else . Cooper Attitudes and rates , t here weren ' t any rat es . The thing was steered right down the s lot . came off smooth . Conrad Spacecraft separation NflD~NTlAk We CONF:10ENT-IA 26 Cooper We separated as smooth as silk just r i ,5ht straight ahead Conrad Well, we counted down and Gordo said h? was ready and I SEP spacecraft and he thru3ted and I went back to RATE COMMAND for them and we came straight off . I didn't even feel it . The first t hing we felt was thrust . Cooper And rolled upright and went to 000 00 - 15 which happened to be right on the horizon. As it t urned out that 15 figure was good . It read out the IVI•s . FCSD REP That's, you know on 4 . . . they thought they came off the booster. 3.2 Conrad Yes, that's why I mentioned that because Cooper That's what we were looking for, too, SEGO Plus 20 Seconds Cooper We've already mentioned the IVI displays . Space­ craft separation occurred very smoothly. Thrusting was smooth , nothing wrong at all . Attitude rates were good. Conrad Yes, I don't understand this! I don't understand this guy saying that they can't hear them or they can ' t sense them. Boy, I was easily aware . . . . .;; FHID~Nf lAL Cooper 1/ than you can hear You can feel t hem almost mo,-e them. .. 27 You can feel them vibrate r eally, more than you can hear them . I mean , you can hear them too , but the vibrat ion you can hear them too, but t he vi bration you can f eel the thrust . Conrad Have you ever heard a high speed hose or high speed water j et. Shhh ... That 's the impression that I had. Cooper Yes, that ' s right. FCSD REP Even from the aft firing thruster? Cooper Ever y thruster we had on t here. Conrad We heard every thruster on the whol e f l ight Cooper It never occurred in my mind when the thrus t ers were fired. You can feel them and I can hear them. I couldn 't hear them in the sense of an expl osive sound or a roar . It sounded like wat er swishing. Conrad Yes , very definitely, more a Shhh . Cooper And I was aware of it again when we made the burns l ater on, you know , we made the reverse coelliptic stuff and all that. FCSD REP How did these noises , the thruster noises , sound compared with the way the last crew set the mission simulator? ' 28 Conrad Hey, that's another i nteresting point. Cooper They're not very close on pulse. Conrad Pulse is a ... Cooper Pulse is more of a thump . Conrad That 's the one sound that does sound like you ' d • expect a rocket engine to sound . Cooper Here ' s a sound just about like this : Conrad Yes , it very definitely sounds like a knock . (knock) There is no "shhh" or roar, just a little thud. Cooper You can hear it just like somebody knccking at the back of the spacecraft . You can hear it go "tap tap, tap , tap, tap, tap," Conrad Really, the simulator doesn I t sound tl:.e right way. It ' s a general enough nature and it tl::.e same type manner Cooper Yes, it is close enough to give you a good cue. Conrad The platform mode for instance , you krow, when i t goes shh, shh, shh, shh ... did the same thing i n the spacecraft except it was all in one thump and swooshes when it was constantly firing the thrusters it sounded like the swish. Cooper The air-to- ground communications I thought was excellent the whol e time. I didn't find anythi ng , ONEl0EtslJl~E 29 wrong. .. Conrad We really had good comm the whole flight. Cooper There was never a time -- the only time the only fault we find was one or two times through the remote site when the MCC was trying to remote to these sites they would get some fading. say the HF worked excellent. I must When they were ~ r ~ u s i c , broadcasting music to us, my\ gosh they had us practically the world round on '-----~ T h e music quality was quite _g0od in most cases. Conrad I got times on that we can bring out later so that they can correlate how far Cooper GO/NO GO , there wasn't any problem on that. They gave us the GO right away. FCSD REP How long did it take them to give this? Cooper Oh , heck, immediately. Conrad Almost immediately. .> vveaf There was no swivel because there was no velocity ~ correction. Cooper There was no velocity correction needed. Orbit quantitites were good, they had those for us. It took them quite a while to read us our experiments but they just said you have a nominal orbit and then mayb_e . . . . . eQNFIE>ENTl~t I Conrad I've got down here the GMT of liftoff . I wrote down ... 13 plus 59 plus 59 which they l ater change to 14 plus 00 plus 00 . I have the one A time they got it up to us okay, which was 10 pl us 11 . Then I have the 2 dash 1 they gave us was 01 pl us 27 plus 16 which they later revised to 01 plus 26 plus 27, I wrote those down. 3. 3 Insertion Activities Cooper Okay, l et ' s start on inser tion activities. SAFE t he swi tches we did that just right for our check­ list . In fact , we are even more convinced than ever that a good, thorough, accurate, checklist is the only thing to have and Conr ad Physically marked them off when they "·e r e done . Cooper We followed it conscientiously. The sequential light t ests, we did it j ust by the teE.ts . Stowage:; . we already had modified our checklistE, ·and we already had written on some of it that we would do these i f we decided to. For instance, the D- rlng safety pin, we did install them at right t i me, and there was no problem on those ; they wer e nruch easi•~r under zero- g to get in and out than we had thought and I had no " .kQt4FIDfNJ1A.L, 31 trouble getting my D-ring in, did you? . Conrad I waited on mine , remember. Cooper Yes , you waited . .. . Conrad I s towed my D- ring thing Cooper So we closed the cover immediately and I decided I woul d go ahead and see if I could get mine, and I got to i t right away and it went right in, so I put it in . Conrad We, of course, got in trouble in the second orbit , but we did not unstrap or put t he drogue pins in the seat or unstow any items of gear other than the flight plan books and the 16mm camera and the Hasselblad. I take it back. We went through the Flight Plan as advertised and then stowed the items. We had D-2 canera out, the Blob out, but we did this in the proper places in the Flight Pl an. But we never did unstrap . Cooper We never unstrapped and never put the drogue pins in until after we go to 6 - 4 GO. We got a 6 - 4 GO. Conrad But we restowed too , after we got in t rouble . throught maybe having to go into 6-4 why, we'd put ourselves back into the configuration We 32 to reenter Cooper were never up . lready decided t hat I was not going to launch with th£~ They are just useless as far as I am concerr..ed, and I as delighted I did not have them; and I didn ' t miss I don't think, I think could remove th€m and Conrad - The arm restraints are there for the pressurized case and high altitude ejection . mine up . I did go with I would prefer to go with thEim down, but there wasn't any reason , I didn ' t need to get my hands on the hand control or anything ~.o I left them as they were, but I don' t think tr.ey were necessary. • " FtDENTtAL Cooper Okay, belts . belts . I couldn ' t 33 ~~ he The harness - While we 're on the harness , I don ' t like that harness worth anything. t hink what we need is a simple type adjustable type harness wi th clips on the legs that you can undo legs to get to some of the functions you have to : uri pation and defecation and so on in the spacecy ft . I do ' t see why we have to have a big, expensi/e, custom, made ha~ss that you can ' t readily get on off and this on~ you can not readily get and if on it and snaps you had one with harness , it would like you do on be, I think, a hundred times useful as this one . Conrad Let me ask you a ~uestion . you r eally - I agree. Do you really - now , do Let me say this . I agree you should firs t be able to get your harness on and off, but in zero- g I ' m not convinced that three , especially two leg snaps type arrangement. In other words , a harness that would come completely loose and have many straps that hitch to the other straps would be really good in zero- g . What I think we need to do is to be able to get in and out of that harness that we have , easier. Like, maybe you could loosen the leg straps on it but not have them come apart . ~ NftDENTrAL Now , I took my harness off in flight twice . I took 1 em " off once-Cooper Yeah, but you wouldn ' t even have to step through these leg loops if you had - just like on an airplane harness . You could undo that and you wouldn ' t eve·'.l. have to worry about the leg loops . Then all you 1 d have to do is just slide out of the torso area. Conrad Yeah. Well» lets sees that ' s what I' m saying. If you unhook both of those leg loops and you throw the whole thing down in the footwell and then you pull it back up again you got a leg strap floating off ever here and you got a - Cooper Well that ' s no problem. ing your lap belt . It ' s no worse i.han it is find­ Did you ever have i;rouble getting your lap belt back on after you took it off? Conrad I always hitched it on the Velcro over on the side . Cooper But you never had any trouble ~ ting t o it. I didn ' t . / I let mine float free and I never had any trouble getting t o them at all . Conrad Well , I just don 1 t lmow now. I really d:i.dn ' t think it was that bad getting in and out of this harness . only concern was that if- - I stayed- - Cooper How many times did you get i n and out o f it? ~ My :: ( OhJFt0! Conrad Twice . 35 The big problem was having you unhitch the straps on my suit . Cooper That ' s right . Conrad The harness--the easiest thing was getting in the legs . With the cables to go over the harness . That was no problem at all . Cooper Yeah. Conrad Where I needed help was getting over my shoulder and getting the straps on the suit hitched back up again, which is a two man operation. Cooper Well , my point is that for normal wearing around the pad area or wearing around when your suited and every­ thing, you ' d be much more comfortable if you could have those straps loose where they ' re not gouging you in the legs , Conrad Yes , well-- Oh, I agree. Cooper Or where you had adjustments on them . ... Conrad . .. adjustments see-- Cooper Okay, well . Conrad Where you coul d make the legstraps loose but you' d never disconnec t them so you don ' t have free floating straps around t here . Cooper It was no big problem .... My suggestion would be to have them exactly like you did in a parachute harness . You have the leg adjust- ment and on that same fitting you have the little snap " wher e you can unsnap in the places you want to . Conrad Oh yes , you dan do it either way. Cooper You cou,Yd either loosen them or--I just thi Sure . we've gone to such complex tailoring devices in orde f ovide some company with a great elaborate pro of providing expensive harnesses that they .. . per- sonally don ' t think they ' re worth a darn for what they're ·ntended for . I don ' t think you gain that much . I think'y~u loose a lot of it . Conrad ~ stow that harness . Cooper The life 7 est. Now I disagree wit said that those aren ' t in the way. everybody that ' s ever e were them all theI time mainly because we didn ' t hav a darn place to s i ore them and they're a pain in the Ii,leck t o get on and off but they are really in the way. @f everything you do . The;r ' re in the way They bump int0 your arms . Tbey ' re there to cut down visibilit on ;rour chest and they ' re just a nuisance, Conrad Yeah , Cooper We didn ' t e didn ' t have a place t them off and left them off . store them. store them or we'd have taken I am here t o say t hat I ONFTDENTl~t 37 think they ' re r eally bad where they are . Conrad After the big sweat was over and we got a GO and we were relatively sure we were going to stay there for awhile unless we , you lmow, had some other emergency come up , I would have preferred to take off the harness and the life jacket and stow it somewhere if we ' d have had a place to stow it . Cooper Right . Conrad But the other thing is that maybe that ' s just my per­ sonal feeling . I ' m extremely meticulous and we kept that spacecr aft as empty as possible . Everything had it ' s place and it stayed in it ' s place . Cooper And that harness and the vest--are pret t y big, bulky items - Conrad And I wasn ' t going to have it rattling around down there on the floor , loose . Cooper Okay, on the drogue pins . By golly, I thought those new l i ttle things on the drogue pins made them very easy to get in and out. There wasn ' t a bit of problem wit h those . Conrad I popped the drogue pins in and out on mine . Coope~ I put mine i n or out once just to ... . Conrad I think Gordo put his own in and out once to see if he could do it and he coul d . Cooper Okay. That worked real well . Fuel Cell o and Fuel Cell Hydrogen Quantity Read . 2 Yes , we read them at least a million times . Power Readings . t hose. FCSD Rep Fuel Cell • Yes , everything checked out fine on Bermuda 2- 1 update : fine . Orbital Flight . You ' d better get out your flight plan on this because t his is the original stuff I was telling you about . Conrad Well , that ' s all right . This probably will go fairly.... FCSD Rep All three , if you go the way you did it. 4.0 Orbital Flight Cooper Okay, on 4 . 0 Orbital Fli ht . Platform Alinement. Conrad There ' s our first problem . Cooper There ' s our first problem. Our plat orm mode did not work and I don ' t lmow what ' s wrong wit darn thing does not zero out but the on the space­ I craft. It allows a good e to sit in there and won ' t zero it out and it is ex remely s l oppy ·n pitch . The whole thing, I think tb7:r was something ~rong with the whole thing because it d esn ' t work at I a \ 1 like the ones in the simulator, an the whole thing plu's or minus a half a degree a very, ver y system thing really wrong with it . lucky to be plus or I personall y think that ... ~ pl&f~T A~ 39 \ something was wired up wrong or something in i t because it was not working right . Conrad We didn ' t really get a chance to evaluate it too well because we had trouble with it so we stopped using it and by the time we ' d been able to do anything with it we had other problems , fuel problems and so forth . So we never did get back to using it again . Cooper Well, we had other control system problems which were overpowering, platform problem wise , but we did try one burn on the platform and it was a terrible mistake . The darn thi ng did not have the accuracy to really hold it and we got one foot per second in and out of plane there . Conrad Yeah. Cooper In one of those , that coeliptic burns and we ~ade our That was in those coeliptic . other burns then on Rate Command and man, that Rate Command system is just beautiful . It holds that space­ craft so tight that it can ' t vary. Conrad Yeah . We had a beautiful control system, I thought . When Gordo made any of the burns on the Rate Command or anything l i ke that it really responded -- well. Coope1: Rate Command has tremendous torqueing. Boy, it ' s strong and it ' s instantaneous and you can just stop it right on the money. Really good. 40 FCSD Rep Okay, on this platform alinement thing. You went to SEF and caged and SEF and Platform Control Mode, Cooper We pitched down to visual when we went to CAGE and then went to SEF and we went to Platform mode and after fid­ dling around with it awhile we decided the Platform mode wouldn ' t work so I went to Pulse and then I , just using my needles , Platform needles then , I just pulsed the er­ rors out until we torqued around and got the ... got it ... on a fine line. Conrad Okay, Now , there ' s no doubt in my mind that the Primary Scanners , there ' s no doubt in my mind now, but we lost on Primary Scanners . We started to aline the primary Scanners and I don ' t think we ever got to platform a line correctly because the primary scanners were not working correctly, Cooper Now the primary scanners, The funny part of it is the Primary Scanner was working in such a rr.anner - working just enough, that it checked right because when we checked out t he alinement of it and the tolerances on it it was working fine , but there was something in it on one of the tests that we did later showed thai it was actually driving, tending to drive the spacecraft down . Conrad Continuing to torque you down to about fifteen degrees nose- down , • . 41 Cooper Or more . Conrad In other words , it continued to try to aline t he platform at about fifteen degrees . It tried to put the nose on t he horizon is what it did . FCSD Rep It tried to aline the platform up at fifteen degrees nose down? Cooper Or more . I figured it was about somewhere around-­ Well , one time it alined us at about 40 degrees nose down and it still was indicating in scanner limits . Conrad The scanner got worse as the flight went on, but I don ' t think it ever worked correctly . Cooper No . I don't think it did , now I look back . Conrad That ' s the thi ng right there and I think that this- I 'd l i ke to know what they decided from tracking the REP on how we put the REP out because we put the REP out in the proper position, but I don ' t think the platform was alined correctly . We had trouble with that scanner in the sunlight on the horizon and this was right when we were using it to aline - j ust before we put the REP out . Cooper Just as we were using it to aline and put t he REP out , the Scanner began to skew all the platform needles off and it skewed off and , --went to ORBIT RATE. L 42 Now wait til we get the onboard tapes because the tape Conrad recorder was working and this all is on the onboard tape ; the conversation that Gordo and I had about that. So we weren ' t really sure it was working right but it f wasn 't that far off that we were going in the dark-Cooper . Approximately 30 seconds before we had to pitch around or had to yaw around to eject the REP, I had to go back to CAGE and try getting a real rapid P] a tform aline in there , SEF and PULSE and I had the neec.les zeroed and we may not have been so far off but you don ' t know . isn ' t enough time to really get it alined. words . That In other I had about the time we did it and got there we probably had maybe , 30 seconds to Plat::orm aline . That ' s about all we had . Conrad Well , we were just hoping that if it had been pulled off only in pitch why, you know , we ' d get it right--we'd pull the pitch right back in again. Cooper But the scanner was acting up very badly by that time . FCSD Rep How long did you aline the Platform initially? Cooper Initially, we alined the platform for about 15 to 20 minutes and it seemed to aline allright although at that time Pete and I had a discussion right then that we seemed to be alining nose down . .. Conrad Now , you see . Here ' s something that I've never heard from the other guys . Cooper Now there ' s another thing. to show us . See, we never had a simulator Never once did we have any darn thing to show us what out the window should look like . Conrad And when the Platform is alined and you ' re zero- zero- zero , boy, oh boy! That ' s a , just -- It's a very peculiar looking situation and it ' s not what I expected to see at all . Cooper No , it isn' t me either . Conrad And I ' ve never heard either Gus of John or Jim and Ed say "Put a little gouge out" Now I ' ve got a gouge tha t I can draw for you where I 'm sure tha t I can put the Plat­ form in roll and pitch within a degree in roll and pitch of where it should be out the window on the horizon and it ' s by using the corner of the window and the RCS thrusters on the front : the front RCS yaw thruster in the lower corner of the window and you can put the Platform-- you can put the spacecraft zero- zero and roll and pitch just, well , like that. We didn ' t know that before we went . Cooper This is one of my strongest recommendations if we aren ' t going to have any kind of a visual out the window display at least we ought to get some of the great planners to • 44 ----- • draw up on a piece of paper what the window , what the ;: horizon should look like through the window whic~ d requested several times and never got -- to show ~~~) guy what these various things should look like out the ......__ window;'---...We spent the whole darn eight days trying to ~rt=--'l;fl:e-s-0--~ ~ ~43 ~ould look like and I'm not sure we were very clear on it to the day we re- entered, Conrad Yeah. Cooper Now that 's ridiculous! And it ' s becau:3e of this odd angle that you sit off in there . It completely fouls up everytning, as to getting these various angles : inverted and right side up and 90 degrees angles and all this . Conrad / 1think we ought t;=-I ' ll tell you i ; ~ d recommen­ dation for the guys who are going to do this on GT- 7 with that Hasselblad can take a pound or two of fuel and sit up there and pl:.otograph the camera back inside the spacecraft get the window perspective in this thing . zero- zero- zero , bank right 90 , bank lnft 90 , at nose pitches above the horizon , <iOt◄r ,e eNirrXt ifferent Really , we sat ther e and had hours worth of discussions in drifting flight when we'd be drifting through , you know , and we ' d say, "Hey, doesn ' t that l ook like they'r:e about 30 degrees nose up and roll right 60 degrees?" and then we ' d try to find those lines and match them and see . . . there ' s an awful lot of learning there . By golly, if we ' d have a Platform Aline Gouge , a visual gouge idea , we'd have picked up this trouble right off the bat. We real ly didn't think the platform. was alined right , but we really didn't have anything to tell us t hat it wasn ' t . Cooper Now looking a t it where we know now after we went to the other scanner finally and we got proper operation knowing what we learned during the flight it appears now like we were--the number one scanner was trying to aline us several degrees down over what it should. Conrad Yeah. FCSD Rep Did you ever go back to Primary after that? Cooper Oh . We checked it a lot of times after that and tried it numerous times and it got worse and worse and worse and it finally was actually driving the spacecraft down to minus 90 degrees and still the scanner, that ' s the funny part of it , the scanner wouldn't go off until you were about 60 degrees below the horizon. 46 Conrad It seems to me we ' ve got some data for them on Primary scanner over the states so they could h~ve it on telemetry, They should be able to find out what happened on that , Cooper Yes , something was really fouled up , I think , Insertion Check List-Conrad We went through it by the numbers , Cooper By the numbers , Thruster and Control Mode Check - we went t hrough by the numbers. Conrad Everything was fine . Well , we were a little bit late, We get a little bit behind and it was about the time when we were late per­ forming the thruster control mode check because that was supposed to be done before you got to the Canaries and we did it after the Canaries . Cooper That ' s right , Conrad We were behind, but we started catchine: up . , ee,~FID El'<ITIAI!Cooper Com Systems Check. We were right on the money, on time , on that . FCSD Rep Everything checked out okay on that? Cooper Yeah. FCSD Rep Com System? Conrad D- 4, D- 7, I did by checkoff list and checked out okay over Carnarvon. Cooper 6-4 GO/NO GO, well , that was quite late . Conrad No. We got a GO for 6- 4 over Carnarvon . That's just to get past 2- 1. Cooper Okay, Yeak Okay, got the 6- 4 GO/NO GO, that ' s right, D- 4, D-7 GO/NO GO . Those were right on the money and everything was fine there. Third adjustment maneuver. Conrad Was nominal Cooper Was nominal end everything was fine there. Power down D-4, D- 7 was nominal . 16mm, 35mm, D-6 equipmert unstowed and mounted and there we begin to deviate a little because just prior to this time we began to get this rapid decrease in the -well- where was it there? Conrad It was - let me go into the log-book here for one second because I got some. - 48 FCSD Rep This Perigee adjust. Did you do that i::1 Rate- is that the one you did in Rate Command? Or is that the one you tried in PLATFORM? Cooper ~ Did that in PLATFORM and it worked fine on that one. Did that one in PLATFORM and it worked ,~eat, but then on some of these other burns we did I tried it in PLATFORM and it really didn 1 t work well at a ll. thing. That 's why I rather suspect the P::.ATFORM There's something wrong with it . I think i t was better at some times than others . It was allowing a lot of drift. Conrad Okay, in the log book I have it at 50 m:.nutes which is just prior to Carnarvon that I found the Fuel Cell o2 and H Heater Circui t Breaker OFF. Now 2 that--I found it off because they told us to heat the Hydrogen not the Oxygen, but the Hydrogen final ­ ly drilled down to the 220 and they want ed us to use the heater and I turned the heater on and I noticed that I didn 1 t get any ammeter rise and so I looked at the circuit breaker panel and the Circuit Breaker was OFF. So, now in ret rospect seei?hg·the o ON which is on the same circuit 2 breaker burned out, I'm sure that it blE,w when this thing burned out, f .. FCSD Rep We were at the power do':m. on the D- 4 and D- 7. Conrad Oh Yeah. Well, about that time I think we were getting back on the Flight Plan. out. We got the 16mm We got the 35mm out. Cooper D- 6 equipment was Conrad Well, it ' s really D-2, it ' s what it was and I had that work so I decided, "I ' ll put together in pieces at the blob and the camera put together separately and they had it all loaded with the right film and everything and had it on the floor, and we were ready to go . " FCSD Rep Were you pushed for time to do this? Conrad We were right on the money. We finally caught up after Canaries and we were on the schedule at Carnarvon. Cooper Yeah. Cooper Radar test #6, at 01 : 30, that worked fine . We were in good shape at Carvarvon . bring it on. It worked . Observed the transients on R dot, range and range rate. load came out fine . We did 6- 4 Preretro command Blood pressure on the Command Pilot there past Carnarvon, let's see . Now that was back over the Cape here, yeah. Conrad No , you broke the O-ring didn ' t you? IAL Right off the :JI 50 bat we broke the 0- ring. Cooper That 's right . That ' s right . one . .. That 's the first We broke the 0- ring and couldn ' t give them that blood pressure . Conrad I think that was the one. Cooper That 's right. We fina l ly gave that one up , The 0-ring was broken on that one. FCSD Rep Let's see . This first blood pressure that you got an hour ... Conrad They got that one and then when Gordo-- Cooper When I, When we transferred over to me and I plugged it in the ... 0-ring broke and ,:e didn't have time for tha t pass again . Conrad We had a bunch more 0-rings . it but we fixed it .. . Cooper Fixed somewhere around there. Conrad ... shortly thereafter . Cooper M-1 experiment . Conrad We turned it on on time . I forget when we fixed 51 .. Cooper Yeah . I got a lot of comments later on that on. That thing is so noisy. Conrad Oh, you know , I found out what happened, you know . They went back and recomputed and they found out they had four days worth of air in the bottle--Ha Ha! FCSD Rep Four days? Conrad Yeah. Cooper But the thing. You can turn it off and it keeps run­ ning back there . And it goes SMACK- CHOO , SMACK- CHOO , It ran out . SMACK- CHOO . .,. Conrad Yeah, it 1 s pretty noisy. Cooper And in a real ~uiet cockpit it really sounds loud . FCSD Rep This radar test #6 here at O1:3O- Cooper Used to turn the radar on. Conrad Used to turn it on. FCSD REP Used to turn it to standby. Cooper Turn it to standby and warm it up . Conrad Used to observe the warmup transients . FCSD REP And all this happened, right? Conrad Yes , and it 1 s on the voice tape. Like Gordo said, you lmow, what the radar needle did , What it does is it has sort of a cyclic thing when you put it in standby and it 1 s ready to run why it sits there and the lock on L 52 l ight blinks Green/OFF, Green/OFF. Cooper Lock on light will blink on and it will come out R and R dot will go from peg to peg. And they 'll settle out when it really is warmed up good and you' ve gotten past the transient periods and they ' ll all come back to zero . Conrad I think what they ' re looking for are clues to tell you that the set is warming up correc t ly. Ba.ck in the early days of TACAN we had warmup problems. FCSD REP In other words , this would be your firnt indication if something was wrong? Cooper Purge Section. One and Two . Conrad Well , we got our first load , this 6-4 load. The first load that came up over the DCS system and it came up right over the Cape. Cooper Purge Section. Conrad Yes , no . Yes . That ' s when we were getting rushed . go back to that . One and Two . Got that? Let ' s stop right there. Let ' s The REP was supposed to go out at 02 : 07 and I purg·ed early and I always had been purging early because I purged it about 1+50 and then I went through the check off list and they were all checked off here. I powered up at 1+50 , I purged the fuel cells and here I checked them off here. . . . prop gauge experiments and the RAD 1 on and the cold 53 IR on and the power on the exmitter on and the recorder off and I went through these by the numbers . Com­ puter, we went to Catch- Up . We had the hundred feet in the window . We were really getting ready to put the REP out and right then and there was when we came over the hill and we were beginning to get to the dark side you know, and the sun was getting low and that ' s when the scanner started going out , Cooper That's when the scanner started dropping out . Conrad And we started getting the scanner light and then now , you got to visualize there ' s part of the problem. We're coming into this "Fuzzy Zone"- horizon and that is the best way to describe it . Cooper Yeah, you can't see anything. Conrad And the spacecraft looks like you're pitched up tremen­ dously when you're zero- zero- zero to begin with and we both had the impression that the scanner was pitching us up. Well , that may not have been true. It just may have been that that's the way the sky got to looking as we approached the dark side zero- zero- zero . Cooper Actually, you have a transition point there where you cannot see the horizon and it doesn ' t look like either sky or earth or anything. It's a complete blank , Conrad It ' s really a grey area. FCSD REP Right at dusk. Conrad Yeah. Cooper Right at dusk or right at sunrise. Conrad Yeah. Now the first time we went through there we didn ' t even see it . insertion . We were working. That wan right after So, mind you , this is the s1~cond time we got to see it and I can' t emphasize thii, point enough, even though we were on the flight plan and everything else, you got to let the guys learn what ' s going on up there. You haven't been up there befor~ in that darn vehicle you've got to learn it . That ' s :right where we started getting in trouble . Cooper That ' s right . That's the exact point t ·:1.at we made . Conrad I made it for six months now. Cooper For many, many months we've made this over this flight plan, sticking this REP, thi s whole REP thing in that early in the Flight Plan before you really have a chance to get the systems ironed out and checked over and everything and if everything goes exactly right and nothing fails you can run through it time and time and time and time again and you'll make it and you ' ll make it on time. 55 Conrad Yeah. Cooper But you add one little failure in there and you ' ve had it . Conrad , Yeah . That ' s where I made my first mistake. We got purged in an hour and 50 minutes and I was going by the check off list and right there we got in this discussion about what was happening to the platform and I missed the most important thing on the check off l ist . got to I for- • st as simThat ' s the whole G-- d-----­ / been running for the D- 4 cold IR, it ' s been our biggest constraint and a thing that I knew as well as my right arm but there was a glitch and the glitch got us off \ - the scheduled activities and I missed it bigger than eek. I di ors on the cold IR and it ' s a ll my fault and I accept the blame for it . We went through this quickie aline business and we got turned around and Gordo had it right on the money, we wer e right out of plane and we got the REP out 15 seconds late. It went out at 02+07+15 and we turned around, waited for one minute, got the radar on, locked on it .. and we were whistling away from it and I was back on the Flight Plan and happy as a clam when I suddenly @OMFIBEt4t4A.L decided that something wasn't reading right and I realized C that I hadn ' t blown the doors on the cold IR and I blew them and at that time the REP was at 25JO feet from us , which is the end of the experiment, but I think it was still reading- Cooper But it was still reading on the, according to the gage . Conrad Yeah . I think that cold IR read to a great, great thing. Now , the Radar gage, this is where--here comes the next mystery- the radar gage said the REP waE leaving us at this point in time and that-- Cooper Five feet per second? Conrad Yeah. I have 3 1/2 feet per second written down . Cooper Oh, at that particular point . Oh, wel:. i t - - when we first got our first measurement on it ·;he range rate on my analog dial over there read exactly 5 feet per second that it was going away from us . Conrad Yeah. Okay. Cooper Right on the money. Conrad To go back to the D- 4 in time it was 0.2, it was 02+ 16+ 15 when I blew the doors , which was corre3ponding to 2500 feet and I ran that REP D- 4 recorder until 02+37+12 and--okay, now. That darn REP! Gordo had the needles right on the REP and that REP was going straight out from us at 270 on the ball . 'COr'1FIDEtfJal>Att It just went , I just 57 , CO► I F 1 DE NJ:1A t thought everything was going perfect . moving The REP was just exactly out of plane away from us and it was moving at about the right velocity and then the mystery came. It just kept on going. Cooper Yeah. Conrad It kept right on going straight out, and-­ Cooper It wasn't slowing down very much. Conrad And I got over here on the graph and I kept reading the mileage and we were up to about 7 feet a second. It was leaving us , and I realized, I began to think , well gee, this is- That ' s when I was really convinced that the platform wasn't alined and we must have kicked it out some screwy way. us quite fast . Then it started to drift : ~ It finally did peak out an ent ) ----------a ~ ...--n:-~---------;---:--:--:-----;------:-:--:;-,i"'T"--,-----,-----r-;-;:--:-:--­ he corner at some phenomenal dis ance , was almost nine tenths of a mile away from us , but drift aft quite rapid and .when we got to the nodal crossing time , it was behin~ ( us by a mile , according to the radar. on radar. Now this is all And now , mind you, it ' s nighttime and it was right there. We could see it plain as day. Cooper Okay, let ' s see, we were at the-- Conrad Okay, that's when we got to this next screwy thing. / See, the REP went straight out and kept on going. Cooper The REP goes straight out and then it just kept on going. It was slowing down very l ittle and just kept on going and going and going and going. Conrad And it never really stopped. What it d:Ld was it sorta, it sorta starting going off this way, you !mow, and it never got out to a node point wh~re you had a definite stopping range and a start back in again. Well , the range rate never got below a foo t per second . Cooper The range rate never decreased. You never got a decrease in range rate , but it just kept- it started drifting slowly of f the 270 line on back out, but it we·nt straight out the 270 line to a- Conrad Cooper What was the range? Do you remember what the range was when it sti ll was out there? Conrad It went straight like relative motion to us would have looked like it went out looking down a plan form, if we were here. It looked like it went out like this and it slowly started doing this . Cooper Yeah. Conrad. And it never did have a stop to it. behind us back in here someplace. It finally crossed C eNftOf " Cooper 59 We never got the point where it crossed behind us be­ cause somewhere when it was about the 210 point was when Conrad we were out of fuel, of fuel cell o . 2 Yeah, well , you see, we went by Carnarvon-- Cooper And this was coming down just BALOOM BALCOM BALOOM BALCOM BALCOM. Conrad See, here we go . We went by Carnarvon. Here I was trying to figure out in here what was going on and what we were going to take out and everything and we went by Carnarvon and right here at Carnarvon and that's when Charlie .. . called up and says check your o2 heater switch to AUTO . Now I had seen it fall , had noticed that it had been falling and I had gone to the AUTO position when without even being told -Cooper You had already gone to nanua.l. Conrad And then I was doing many other things and I decided it wasn ' t coming up and so I'd gone to manual and held it over there a couple times and sort of looked at it and -- Cooper That didn ' t work either. Conrad I must have kidded myself into thinking that I was getting something out of it, and then I forgot it again and then~- 60 Cooper :But you did go back to the AUTO. Conrad Yeah . I put ii; back in AUTO , you know , and then I called t hem, I think it was on the tape and I think I told them, I said, the S'f!litch is on AUTO . We're okay. Don ' t worry about it and then right aft er that we got up to this 240 or so in there and we realjzed that something was wrong and the heater was out and I guess we told them--We told them at Carnarvon that t he heater was out . Cooper Well, we checked at that time then on ·~he annneter on and off and on and off t hat on both manual and AUTO and it was obvious . Conrad And that ' s when we-- Cooper And it was coming down so rapidly that it looked like very shortly thereafter we were going t o have fuel cell stoppage.. Conrad We were getting below 200 and falling pretty fast and we had a big discussion between ourselves and we just made up our mind to forget the REP. We felt we were really in trouble. Cooper So we elected at that point to start rowering down because we knew that we were using fuel cells a t a very high rate . Conrad And we secured the Platform and Radar and everything else. ~ Cooper r ENTI~ - 61 So we said okay and we ' re stopping it right here and of course about this time we were in the boondocks area away from everybody as always occurs. Conrad We were between Carnarvon and Hawaii . Cooper And--so we just started powering down everything and holding on. Conrad So from there on we were off the Flight Plan. Cooper From here on to the next twenty orbits the REP was right with us. Ha, Ha, Ha ! Conrad That ' s what I cam't figure out . How did it get 375 miles from us when it hung around f or 5 orbits? darned thing. That Everytime we went on the night side- Cooper It was so-- Conrad As a matter of fact, I didn't see it for a time or two and then all of a sudden, the nose of the spacecraft was lighting up ! Cooper We even saw it in the day side . It was so near we could even see it in the day side and at the transit areas when the light woul d be shining on it we ' d be just going into the darkness we could look back and you could even see i; the dipole on it as it tumbled. .. The tumble rate was very, very slow. Conrad And then you guys called up and told us it was 375 miles 62 C Cooper That s impossible. 1 away. That thing wasn't that far It hung right in there. Cooper I think that 's the whole things . Cooper But 1 1 11 tell you there were two differnnt night sides we went into. Conrad Several- - Two different night sides- -well , I reaU y-- i t wouldn 1 t have surprised me if it had hit us. Cooper Me either. It seemed to me like it was a lot closer. Conrad That 's what made me think that well, th? platform was aligned and I don't know what exactly happened. I did notice that it sort of climbed on us. So then I had the feeling that maybe it was doing sort of a figure eight type thing. That maybe we had fired it off up or down a little bit yoQ know . .And it was in three dimensions ; a little bi t out of plane working it's way around us , backing up and going a.head and coming back around because the darn thing was always there . It was there until the darn lights burned out on it. Anyti me we wanted to find it if you wanted to move t he spacecraft around you could find it out there . EOl"'lf!ltJEt ◄ =F hA. L Cooper It was close enough so that almost any attitude you were in you could see i t shining on the spacecraft. Even if it was clear back out here you could see the nose just lighting up from it. Conrad So I know it couldn ' t have been too darn far away. I mean maybe up to five miles or something l ike that , but it didn ' t get that far away from us . don ' t understand the 375. I I was really surprised that those guys called up and said it was 375 miles away. 1 Cooper Yes. Well , I don't believe that figure. Conrad It will be real interesting to see what they dig out f r om it . Well, all the radar and everything we had is on the tape , isn't it? Cooper Well, that was our first big heart breaker . Conrad We ought to be able to put that all together . Cooper After all the work we did on t he REP , then not to pull the rendezvous out , we sure-- Conrad Well , from there until we got the GO to 6- 4 we just were along for the ride . Cooper . We just stayed-- I knew that--I was just so sure of all the time we put in simulating that darn thing I just had a queasy , uneasy feel i ng that maybe we better put 64 in more time on other things . That something was going to go wrong-~ Conrad I felt every problem that we had I felt real good about the fact that we had either t he smarts t o lmow that it was straight forward-- It didn't take too long to figure out that that h1~ater was on one line, both heaters , and that we'd had a single point failure. And as a mat ter- of - fact we t ook the schematics out. Cooper And there's another argument for our ha-ring it;' for when it occured there wasn ' t anybody around to ask advice . Conrad I t was very straight forward to throw t he switches and look at the amp meter to see whethe:c you were getting anything out. There was no dou·:it in my mi nd that it had burned out and the sam,= daml thing with the thrusters. When we finally decided we had a problem with them we went through the ci rcuit breakers just like we did in th= trainer and it was obvious that number 7 was out and 8 went out and then the rest of them started getting sour. So, I think that all the training we had we were pretty well prepared. Cooper I do , too . I ' l l tell you- - the launch- -we were perfectly normal and right on the money-Conrad Yes , we were sitting there waiting to find out what they wanted us to do . I mean we !mew we could go on the batteries long enough to get to a fairly decent re- entry place and we wer e taking bets wi th one another and we were kidding about McDivitt. There must have been real pandamoni um at MCC . They were burning up the lines to every­ where . Because ther e r eally wasn ' t anythi ng we could do after that but just sort of wait . We re- stowed everything and we were ready to go i nto 6- 4 if they wanted us to . We wer e all prepared to go i nt o 6- 4. We didn 1 t want t o. Cooper We really didn 1 t thi nk we ' d make 18-1. Conrad Gor do was the eternal optimist though . I ' d s ay , " 125 pounds" and he'd say, "Well , it ha sn't really fallen anymore . 11 Then it would fal l about another 20 pounds and I'd say, "Wel l , that ' s 100 pounds now ," and he'd say, "Well , that's really not much bel ow what it was before ." I think we had a little more confidence than the guys on the ground , I really do . I r emember old 1':0 NEIDEbll IAJ. .. 66 Steiner saying don't worry about that liq_uid going through that heat exchanger . will go through just fine . He said it The one thing that I thought was that we might have dinged the tank with the REP but as long as the q_uantity stayed up there we were in pretty good shape , but I wasn't sure that we didn't just might have sorre sort of a hole back there and were just slowly leaking pressure even though the q_uantity-Cooper That was one thing--we always worried E~bout that REP with that big diapole hanging out. If it skewed up a little going out what woulcl it wipe out going out . It just happened to be with a lot of that OAMS--fuel cell lines and all 'Ghat type stuff back there and that was one thing that always kind of concerned us about ejecting the REP now and then. So that was one thing we kept running )ver and wondering what i t had wiped out . Conrad Yes. That was the only thing that kept bothering me , but it held to 60 though and that was pretty good. Cooper Okay. Let 's see boresight on REJ?,nodal crossing. We didn't get the nodal cropsing. toNFll)Et~t1'1L I · sure wish we : COMflDEN I IA[ » could have hung on long enough to find out where i t crossed us behind there . FpSD Rep Let's back up just a minute on your lock on . Cooper Okay . Boy, it just clung right on to it and zap. We got the lock on and the darn range and range rate came right on there . It was moving right out at about 5 1/ 4 feet per second just throttling right down the old line . Conrad Address 69 was reading just fine. Cooper Everything was right on the money. Conrad Address 58, 59-- Cooper The range was moving right on out just like it should and we were sitting right there on our 270 point on the ball tracking right straight out for a long ways out . Then is when the variance came in, when it kept going out . It should have started slowing down on range rate . But , it seemed like it was slowing down awfully slow . It seems like the range rate kept on for quite a ways . Conrad You know I had a 58 ,of -63. 8, and a 59 of a 13~8 at .89 miles and we should have never gotten that far away from i t ever--in the beginning. Cooper See with it moving out at the R that we had, all the figures we had ever run on it--we had our own 68 little calculations right here--finally we were off our graph up there, weren't we? Conrad Yes . Well , you ' ve got to realize that the graph ' s based on out of plane and this was the hypotenuse to the thing, but even so-Cooper But s t i ll you 've got to-- Conrad It still went away more than it should have . Cooper Because you cosine angles were fairly 13mall in t here . Conrad It still went away more than it should have. Cooper I don't quite understand it. Conrad We 'll know what the platform--I presume they can t ell how well we had the platform al igned . Cooper But there again, there 's the f irst little horse shoe nail that throws the glitch in things. When that darn s canner s crewed up right at the most crucial time . It probably had been screwing up all along , we just hadn 't really caught it . It really threw the glitch in right therEi at a point when it really shouldn't have. We ma~, have lucked out still , and gotten . it out right on the money and it may not have been the problem. I don't know, but anyway with the best we had to work with we got it out the best we could and it looked like = • it went out in good fashion . I think we s till would have been all right if we had gone ahead and done the rendezvous with no problem even if we had gotten a little out of plane with it we could have handled this later on. But, there again it made it difficult for Pete because it got him completely off his schedule , too . Conrad It got him late blowing the doors . Well , we s t ill were reasonably well on top of it . Let ' s see . We can skip all this REP s t uff . You got anything else you want to lmow about the radar? FCSD Rep It would be best I think to go on through it and say what you did and didn ' t do so we can stay on this . Conrad Yes, well-- FCSD Rep Use your flight plan. Conrad Well, we got as far--let ' s see, it says when on bore- ­ sight read and record address 58 , 59 , and 69 and this was just before 2: 51 when we were supposed to have a reading to give back on the ground. This is the reading I got: 139 . 8 . 58 read -63. 8, 59 read The distance was-- address 69 was .89 miles and I got that at the t ime that it was supposed to 70 be gotten, Cooper Why don' t you bring the flight plan over here and let's start down it. We might as well s kip what he has in the flight plan here because it varies so from there on. Conrad From here on you can for get this flight plan . Cooper That ' s right . Conrad Right here . Cooper Where 's our little book of the fl i ght plan? Conrad I've got i t right here . Cooper Oh , okay . Conrad Okay. All this time we sweated out getting home and that ' s when we wound up-- here is where we s t arted on this flight plan, at 1 day a nd 02 hours, so that's 12 hour s after lift- off. Cooper We finally got back on A f light plan ani -- Conrad Yes , and that ' s the first thing we started to do was to power back up . FCSD Rep One day. Conrad No . Cooper We star ted that one day-- Conrad We went CEl' to 2400 Zulu and then tha t became day 1 , 00 hours and lift-off was 1400 Zulu. That's 24 hours . That one day remember we-­ CO N·rrD Et ◄ ifI,A. L~ " Cooper From lift- off until 2400 hours the day of launch was elapsed t ime and s t arting a t tha t t ime we started calling it day one and then GM!'. Conrad Okay. So , we went through a l i ttle deal here where we started to power up and they let us tum- ­ we'd been drifting hadn ' t we? Cooper Yes . I ' ll say. Conrad We turned up the AC , ACME inverter on and the ACME bias power on OAMS attitude on and we went t9 pulse and we were supposed to power back down again at 02 + 27 + 25. We were supposed to have this H 2 purge a t 02 + 45 + 00 . Tha t was the first thing, they were just going to let us purge H we 2 didn 't purge the o:xygen. Everybody was worried about that . Then we were on the flight plan and they gave us an update time for our first medical pass and we stayed- - ! think we took these vision tests , didn ' t we? Cooper Yes, we did . Conrad We just stayed right on the fli ght plan , had the vision tests , and I have a comment in here that at 01 days 04 hours and 32 minutes we saw our first Cooper meteor r e- enter . ~an , we saw a lot of those meteorites re- enter €Or<tFlt,fN I i.2u 72 below us . • That kind of startles you when you :: realize they are 9ntering below you. you . ve Conrad This is when the exp minds . It means imenters went out of their They handed us this flight pl8l1 you wouldn ' t believe where they had 1, 2, 3,4,5 , 6,7,8,9,10 , 11 , 12 , 13,14 , 15 , 16 ,17,18 , 19 , 20,21 22,23, no 22 experiments they gave us to do in a row an they ir.volved everything in the spacecraft anti we had gear all over . You wouldn ' t believe it . much junk--we went wild. That I never had so '/s when we called up and said, "Hey, gang let ' s be a l i t·~le more reasonable." Cooper The other problem didn't list them seque Conrad Yes , that ' s right. Cooper They put them in there and we had to keep skipping around on them to get the sequential time on them and that was a mess . Conrad Now, what we did is we copied down in this book and then we'd write it down at the proper time so that we had it sequentially in the flight plan. Cooper It worked out very well . NFIDE • Conrad 73 You , don 't want to get into which experiments we got done and which ones we didn't or do you? Do you want to go through it that detailed? FCSD Rep Well, there's an experiment section in there . Cooper Well , let's cover all the experiments in the experiment section . We might just comment right now how that I think our book arrangement worked out extremely satisfactory and I don't know how we'd have ever kept up with where we were if we hadn't had these books to follow . We just passed these books back and forth and we managed to keep them stowed pretty neatly. where they were . I knew r ight Pete· kept them stowed beside his left leg in the seat. They slid right do~m the seat. Conrad Right here and Gordo kept them on his right and if he had them and I wanted one -- Cooper If he was asleep I would just reach over and slide them out and vice-versa. And then our Volkswagon pouches held the l i ttle ones real fine . These books were used a jilli on man- hour s-- just back and for th . They really worked out well. They're easy to write in and we tried to keep meticulous logs on everything and I think we did reasonably ftBENTIAt , L well . Conrad Okay, now we also wrote in these little screwy ditties . This is where we kept the things if they wanted us to power-up something or pull one of their nutty tests that they dreareed up in the middle of the night . We ' d write them down just in order in which they came. Cooper Do we just want to go right on down thrcugh here? FCSD Rep Okay. Why don ' t we go right on down anc. list what we did and then when we get in the experiment section we can go into detail . Cooper Okay. Where did we leave off here now. one day 4 hours and 40 minutes . At--okay , Let' s flee we didn't do this-Conrad No , we didn't do the cryogenic test . Cooper Then at 1 day 5 hours we did the S- 8 , I)..13, Connnand Pilot. Conrad That's another thing. Tnt's right. They had you doing these things while one g.:;.y was asleep' and one guy was awake . You wake up and have a briefing period just a bunch of baloney. We were both awake and when we took a test why we took it together and got it out of the way. Cooper l,'e ate together and slept together and took the •.•. together. We'd been completely st~rtled it's 75 wi th terrible pulse rates when we ' d hear somebody calling from down in that deep barrel , Gemini 5, Gemini 5, Gemini 5. Ha ,ha. Lights on all over the place trying to find the radio switch. Cooper Okay. Ha- ha. Out of a deep sleep . I think maybe if we'd just go down through here and hit these things that particularly-Conrad Tell me where we are in time and then I'll look in here to see what notes there are in here . Cooper Well , and then we left these pretty well as we went through the flight plan here and then we left those pretty well-- Conrad Well , these are all the next day s o-- Cooper These things are all ready listed in there--I think were just mainly the things we wrote in here . Conrad These S-6 passes Cooper S-6 weather pass at 1 day 6 hours and 10 minutes . 1 day 7 hours 48 minutes 26 seconds . G8, we did that . Sequence That was the hurricane too wasn' t i t? And then we had another sequence on that -the next trip around at 9 hours 22 minutes 49 seconds . We looked at it again. Then at 9 hours 27 minutes 33 seconds we had a sequence 208 and that was-Conrad Man, we've got logs for the logs. "C O ► li 1DENJl4,L 76 Cooper I don ' t know but what we might be better on this just to go through our individual specialty logs and log where occured at what time , because that's the more accurate one of all--because this was kind of our running logs of what was going on--to warn us when things were coming up ahead. As far as going back into this and doing the whole thing that isn 1 t as accurate as going into-- there are so many specia:.ty areas in here . We have those logged real accurately according to time. I think :.t might be better to go through and get a:.1 those and build a flight plan out of that r ather than go through the flight plan because the flight plan had to be just completely- -we didn't sleep when we were supposed to and we didn't eat when we were supposed to and-- . Conrad Well, let's go on through this thing, and now as far as the experiments go those guys have a complete log of what they sent up to us and that should jive with the complete log that we have of what we received and from that and what we logged and what :: 77 we did we can tell you at any point in time whether we got a certain experiment done or not. If they want to know if we got something done or not and if there's a reason why we didn ' t do it why we usually had that recorded somewhere. Either in here or in the flight plan. Why don 1 t we go through this one? Cooper Okay. Conrad When we get to a point of the experiment or s ome­ thing we can check in here . Cooper We did the UHF test . FCSD Rep Why don't you read off those days . Cooper Okay. One day and 8 hours--let 1 s see 1 day 10 hours 49 minutes . Sequence 03 UHF test 3. Conrad Right . Cooper We did that . Conrad We had--were supposed to do an Apollo a t 01 12 36 17 , Cooper Now I don't think we got that one. I think that was sequence 208 . Why don't you check that one real quick--yes. I think that was the one we couldn ' t get because-­ Cooper We had weather over that one . Conrad Covered by clouds . Cooper Okay, we had UHF test number 3 at 10 hours 49 minutes . 78 FCSD Rep One day? Cooper We've al l ready mentioned that one . that one. :: We did get We have that one written up here actually i t occurred around down here. plan up- date . Flight Yes, we had lots of those. Conrad Now, here was the D-4, D-7,421 . Cooper D- 4, D- 7 421 occuring at 1 day 12 hours and 7 minutes . Conrad I ' ll tell you whether we got it done or not . Cooper We didn ' t do that one . Conrad I don't know why we didn't do it . No. We were in drifting fl±ght by then, I guess . Cooper Then we have a note right here. The D- 6 number 19 scrubbed for the State side pass . scrubbed that one . They There was a weather problem on that one . Conrad Yes. Cooper Yes . Conrad Okay now this is an interesti ng thing at 01 days 14 hours , completely different than GT 4, we started getting these RCS hea ter lights. Those guys--the only time they got an RCS heater light was something like day 3. Ed said. it was in ring A and he turned on the heater a.r.d he got : 79 the light 2 or 3 times and he turned the heater off then it ca.me on again. You lmow , for an hour's per iod of time and he nBver had the lights again. Now, this is another reason why I suspect this OAMS system-- one of the biggest mistakes ever made--whoever recommended it on the ground to power down that OAMS heater to save electrical ener gy foul ed our whole system because we started at this point time having RCS heater lights . I checked for 8 days throughout the flight and I could always get an RCS heater light. If I turned off that heater switch I 1 d·have an RCS light come on every once in a while and so we left those RCS heaters on all the time. Cooper From one day and 14 hours the RCS heater were on the whole flight. Conrad You lmow they're auto . And the only heat when necessary, but every time we turned the heater off we wouldn't run for an hour or two that the light didn ' t come back on again and it would either be on ring A or ring B.
