Sighting Report — North Truro, Mass, 3 December 1953

This document consists of a series of military communications regarding an unidentified aerial phenomenon reported on December 3, 1953, near North Truro, Massachusetts. At 2307Z, a B-25 aircraft reported a visual sighting of an object that was simultaneously tracked by ground radar and an F-94-C interceptor's airborne radar. The object was described as having an undetermined shape and size, exhibiting erratic altitude changes and speeds exceeding 700 mph. It was located approximately 10 miles north of the observer at an altitude of 10,000 feet, maintaining a heading of 030 degrees. Weather conditions were reported as clear. The 762nd AC&W Squadron at North Truro initiated a report, which was subsequently processed by the Air Technical Intelligence Center (ATIC) under Project Blue Book. Military officials attempted to verify if the radar returns and visual sighting could be attributed to conventional aircraft in the area at the time, but the requested information was not provided to the investigators. Consequently, the official conclusion remained that the sighting could not be definitively attributed to a known aircraft, though it was categorized as a possible aircraft observation due to insufficient data. The document includes several administrative message forms, reflecting the internal coordination between the 762nd AC&W Squadron, the 32nd Air Division, and ATIC to investigate the incident. The correspondence also notes a correction to the message reference number from AFOIN-ATIAE-12-7-E to AFOIN-ATIAE-12-3-E.
