Project 10073 Record Card and Related Correspondence — Alaska, September 1958

This document collection details a series of UFO sightings reported over Alaska on September 27, 1958. The reports, consolidated under Project 10073, describe a round, glowing object with a long trail that appeared to disintegrate. Witnesses, including civilian and military personnel, described the object's colors as ranging from white to blue and green. One witness compared the object's size to that of a full moon. The object was observed from both the ground and the air, with reports indicating it moved in various directions, including south, northeast, and west to east. Despite the variety of flight paths reported, the consensus among observers was that the object left a long trail and, in several instances, appeared to emit sparks or flames. The duration of the sightings ranged from one second to two minutes, and no sound was reported. The Air Technical Intelligence Center (ATIC) requested that the 10th Air Division (Defense) coordinate with the University of Alaska to determine if a large meteor had entered the Earth's atmosphere. Subsequent correspondence from the 10th Air Division (Defense) confirmed that the University of Alaska had no information regarding any natural phenomena occurring at the time of the sightings. The official conclusion recorded on the Project 10073 record card is that the observers saw a meteor, though internal intelligence assessments also noted the possibility of a meteorite or the reentry of an Earth Satellite Vehicle (ESV).
