CX)LIB? TS OF 'IH PREPAR:m:i OFFICER:
4. The check on the lighted weather ball oon showed that it was launched at
14322 and had asc ended to 20 , 000 feet at 15002. It as lost fr vie at that t:im .
It ' s ascension rate as somewhat slower than standard . onnally a weather balloon
would be near the Z7 , 500 foot level twenty- eight ( 28) minutes after launching .
5. If the weather balloon had ascended no ally, it would have been much higher
tha!l the altitude of the reported sighting . If the balloon had malfunctioned and
leveled off or descended, it could possibly explain the reported UFOB .
