Project 10073 Record Card — Miho AB, Japan, 14 July 1960

On July 14, 1960, at 0103 local time, an unidentified aerial phenomenon was observed two miles east of Miho Air Base in Japan. The object was described as oblong in shape, ranging in size from a dime to three-quarters the size of the moon. Its appearance was noted as pale yellow, transitioning from brilliant white to pale white, and it possessed a short tail. The object was observed for a duration of five to six seconds, during which it descended at a 45-degree angle along a flight path of approximately 135 to 145 degrees. The estimated speed of the object was 10,000 mph, and it appeared to be burning as it disappeared from view. The sighting occurred under clear weather conditions with visibility of 10 miles. Official analysis conducted by military intelligence units, including AFCIN-4F3 and AFCIN-4E1, concluded that the phenomenon was a meteor. Satellite reentry was ruled out, and radar analysis provided no corroborating data. The report notes that the reported speed was considered excessive for an aircraft, and the overall description and duration were consistent with meteoric activity. The document, identified as IR112, was processed under Project 10073 and subsequently returned to the 4Bla-Library.
