PROJECT 10073 RECORD CARD - 5 September 1958

This document consists of a Project 10073 record card and an associated 'Operational Immediate' cable dated September 5, 1958. The report details an unidentified aerial phenomenon observed at 0606Z on that date at coordinates 29.03N 63.56W in the Atlantic. The object was described as a 'bright light' moving from East to West. The sighting was reported by a Pan American Clipper (flight 207) and was also tracked via radar, with a report of 350K (knots) mentioned in the cable. Despite the radar contact, the documentation is sparse. Handwritten annotations on the cable express frustration with the lack of detail, specifically noting the absence of information regarding the object's shape, size, elevation, azimuth, and color. The official conclusion reached by the Air Technical Intelligence Center (ATIC) is that there was insufficient information to identify the object, though it was suggested that it could possibly have been an aircraft. The document serves as a record of the military's attempt to process and evaluate reports of aerial phenomena during this period, highlighting the challenges posed by incomplete witness and radar data.
