Sightings of Flying Saucers or Unconventional Aircraft

This memorandum, addressed to the Director of Central Intelligence by Herbert Scoville, Jr., Assistant Director of Scientific Intelligence, summarizes the debriefing of four participants who observed unidentified aerial phenomena. The witnesses reported observing a greenish-yellow light at 1310 hours, which they described as a shadowy object with a single light, later appearing to have two lights resembling eyes. The observers noted the object was rotating or whirling during its initial trajectory. One witness reported a triangular object with three lights that appeared to be ejected from a launching site. The memorandum concludes that these observations can likely be explained as stray climbing aircraft or missiles. It explicitly states that the evidence is not sufficient to conclude that the Soviet Union has developed or is operating a radically new type of aircraft.
