AI-Generated Summary
A series of sightings at Kadena Air Base in September 1960 were investigated under Project 10073. The object was identified as the Echo I satellite based on its flight path and timing.
This document comprises a Project 10073 record card and associated military communications regarding an unidentified aerial object observed from Kadena Air Base, Okinawa, between September 5 and September 7, 1960. The object was described as a star-like, bright light that shifted in color from reddish to white and back to reddish. Witnesses reported that the object appeared to follow the curvature of the earth and moved in a southeasterly direction, maintaining an elevation between 30 and 40 degrees. The observation lasted approximately 10 to 20 minutes, with the object eventually disappearing behind clouds on the horizon. The sighting was reported under clear conditions with a full moon. Subsequent analysis by the Aerospace Technical Intelligence Center (ATIC) and other military units, including the Air Force Cambridge Research Center, concluded that the object was the Echo I satellite. This conclusion was based on the consistency of the object's flight path and the timing of the sightings, which occurred at intervals of approximately two hours, matching the orbital characteristics of the Echo I satellite. The report explicitly rules out other astronomical phenomena, radar contacts, and conventional aircraft or balloons.
