Project 10073 Record — Miho AB, Japan, 28 October 1954

This document is a Project 10073 record detailing an Unidentified Aerial Phenomenon (UAP) sighting that occurred on October 28, 1954, at Miho Air Base, Japan. The report describes a single, round-to-oval, brilliant white object observed by two pilots from the 17th Bomb Squadron, who were noted as reliable and conscientious. The object was observed for approximately 45 seconds through 7x50 binoculars. It was initially spotted at a 12-15 degree elevation in the south-southwest and climbed to a 20-25 degree elevation in the southwest. The object, which emitted no sound and left no trail, appeared to pass in front of a cloud layer at 21,000 feet, growing larger and brighter during the observation. After 45 seconds, the object made a right-angle turn to the north and disappeared behind a cloud at 4,000 feet. The observers noted that the object did not emerge from behind the cloud, despite their continued observation until darkness. Radar checks conducted approximately one hour and fifteen minutes after the sighting revealed no unusual blimps. The report explicitly states that the presence of clouds behind the object ruled out the possibility of a star or planet. The conclusion reached by the reporting officers was that the object remained unidentified, as the motion of the clouds could not account for the object's behavior as described by the witnesses.
