The object was sighted at a 45° angle northwest from the location of the observers at a very high altitude, so high that the object was compared to the flat head of a pin held two feet from the eye. Speed was estimated at four times the speed of a jet aircraft with accompanying sound similar to the USAF F-86 jet at high altitude. There was no change in sound tone or volume during maneuvers. Umusual maneuvers made by the object were; (1) - Three (3) 360° tight turns to the right, taking 2 to 3 seconds to complete each turn; (2) - Two (2) right angle (90°) turns, first to the right, then to the left; (3) - The object slowed down to almost a complete stop, then accelerated to high speed again, making this maneuver twice. The object then rose vertically and disappeared from view. Total time of observation was estimated to be between 60 and 75 secondse There were no radar contacts with this object. No other obser~ vations of this object are known to have been made, 4 \, APPROVED : y /\ x < Mt ) \ j at 3 r : \ | \ | “HARVEY C.
