Begin tert of report on AF Form 1i2—Part II.) 1, On 27 April 1950 at 1430 hours item time, 2nd Lt James Henry Petty, AO- 1909758, departed from Misawa Air Base, APO.919 in an F=80C to join his element leader over Camp Haugen at 25,000 ft. Lt Petty was scheduled to fly observer for the element | leader who was to practice instrument flying. 2, The F=80C EERE was at 25,000 ft, orbiting to the left, indicating 320 mph, The unidentified aerial object was observed at the 2 o'clock position, ten (10). miles INE of Camp Haugen (40°30'N - 141930'E), The aerial object was first sighted at 1445 as the pilot: began a turn to intercept his element leader who was approximately three (3) miles anead, circling to the left, When the pilot was close enough to the lead - aircraft to identify it as a 7th Fighter Bomber Squadron aircraft by the color of the ship's nose, he suddenly noticed that it seemd to be towing a target. However, he knew that their squadron was not firing aerial gunnery that day. The pilot was rapidly |} closing in on the lead ship and to avoid hitting the supposed target, he gained alti- tude and slid over to the other side of the object. The pilot had the object in sight for a total of 25 to 3 minutes and had a very good look at it from the top and both sides. 3e The object was rectangular in shape, approximately twenty feet high, sixty feet long and not over two inches thick, It appeared to be made of muslin and was cream colored. The sun. was bright, but there was no reflection from the object. It idid not seem to have any density at all. Ao The object appeared to be tracking the element leader's aircraft and when first observed, it was approximately 1,000 ft below and behind the lead aircraft. The object then accelerated and moved up to a level position with the lead aircraft and re- mained in that position during the orbiting turn to the left from 45°to 260°, at which point the object accelerated and took up a new heading of 330° and broke away at an es- timated speed of 600 mph, bay There was no evidence of exhaust as there was no apparent means of propulsion, The object did not wavevYor flutter. The object was first sighted against a background of clouds, but as it broke away from the element leader's aircraft and faded from view, it was observed against clear sky, The object seemed to be flying at 275 to 300 moh when first observed and accelerated to 600 mph as it broke away. 6, The pilot could not believe what he had witnessed and surmised that he was getting Inewsoxia, ‘the pilot increased his oxygen to 100% and joined his element leader, The join up was not erratic and there was no other indication which would indicate RYROX1G » 1 The pilot appeared to be conservative in his statements and preferred to think out answers rather than give snap statements, The impression received was that _ » | DISTRIBUTION BY ORIGINATOR FAF 1 cy DECLASSIFIED ~ ye 6 cys USAF Metro “3 pulae . : yy. 4A Cui eS a . ’ NOTE: "HIS DOCUMENT CONTAINS INFORMATION AFFECTING THE NATIONAL DEFENSE OF THE UNITED STATES WITHIN THE MEANING OF THE ESPIONAGE ACT, 50 U.
