Keyhoe learned of this event quickly, got the essentials correct, and incorrectly placed it at April 29. He also noted that “two other discs, smaller types, were watched from five observation posts on hills on the proving ground. Circling at incredible speed, the two discs paced an army high-altitude rocket that had just been launched, then speeded up and swiftly outclimbed the projectile.” Hall 1988 reprinted the full CIA Report in his appendix.
