12 $ ^{0} $ 52' North, when he sighted an unidentified object approximately three (3) miles east of his position and at an estimated altitude of 1000' heading 360 $ ^{\circ} $ . The object appeared to be a flying wing aircraft, its shape resembled a half moon. What appeared to be a dorsal fin was barely perceptible. The span of the object was estimated to be 30 feet, length 20 feet. The object was silver in color. Upon sighting the object, Lt. Meyers immediately started a left turn with the intention of intercepting and to more positively identify the phenomena. While Meyers was making a 240 $ ^{\circ} $ left turn, the object made a 90 $ ^{\circ} $ left turn, then leveled out on a heading of 270 $ ^{\circ} $ , accelerated rapidly and disappeared from sight in approximately 5 seconds. There was no sound heard, and no exhaust trails were observed. St the time of the sighting visibility was unlimited, scattered cumulous, base 3000 feet, tops 6000 feet.
NOTE: Because of the distance from which the sighting was made, no distinguishing features, i.e. power units, landing gear, armament or cockpit were observed.
The interview with Lt. Meyers indicated that he is a reliable nonexcitable individual who appeared quite positive in his statements. He was the only witness to this incident as he could not contact his wing men since his radio was out. Apparently the maneuvers performed by his three (3) wing-men prevented their observation of the object. Official release, from the pursue collection.
