ATIC FORM 329 (REV 26 SEP 52)

Received by AF Form 112. A chectl

by this hq w/ADC WX Service re-
vealed that four balloons our o
Vernallis, Calif. were in the

Montana area, location unknown
due to failure of telemetering

equipment. It is known that thes

balloons were at a presettalti-
tude of 40,000 ft, It is the

opinion of this hq that this
sighting was possibly caused by
two of these balloons.
