1. Subject rep enough radar da ta for an analyses
to be made.
2. The only reference to radar is in Item (B)(l) wherein it is reported
that a total of 57 separate targets had been picked up on the radar scopes.
Assuming that they are based on authoratative knowledge of the existence
of such balloon devices, Maj. Busalachi's comments in Item (K) are concurred
with.
