Project 10073 Record Card — Saigon, Viet Nam, 11 May 1958

On May 11, 1958, at 1120Z, a sighting of an unidentified aerial phenomenon was reported in Saigon, Viet Nam. The observation was made by Sergeant Donal I. Rondeau of the U.S. Marine Corps and Captain Wilford L. Harris of the U.S. Air Force, both stationed at the American Embassy in Saigon. The witnesses described the object as having the appearance of a 'head of pin' with a yellow-orange color and a trail of white vapor that dissipated rapidly. The object was observed for approximately two seconds, moving in a straight path before disappearing instantaneously with a bright light. The weather conditions at the time were reported as clear with unlimited visibility. The report was filed under Project 10073 and followed the reporting format specified in AFR 202-2. The official evaluation by the Air Technical Intelligence Center (ATIC) concluded that the description and duration of the sighting were typical of a meteor. The report also contained a query regarding the possibility of the object being a Russian satellite, though the final assessment remained consistent with a meteor identification.
