Project 10073 Record Card: Sighting at Otis AFB, Massachusetts, 10 October 1952

This document consists of a Project 10073 record card and an associated teletype message regarding an unidentified aerial phenomenon sighting at Otis Air Force Base, Massachusetts, on October 10, 1952. Three airmen—S/Sgt Richard W. County, A/1C James M. Barren, and A/2C Edward P. Robinson—observed a blinking white light from the porch of the airmen's barracks. The object was reported to have flown upward, engaged in a pendulum-like motion for approximately 15 to 20 minutes, and then departed by shooting straight up at a high rate of speed. The witnesses noted that the object made no noise and displayed no visible means of propulsion. The sky conditions were reported as clear with unlimited visibility. The teletype, sent by the 4707th Defense Wing to the Director of Intelligence at USAF and the Air Technical Intelligence Center, notes that an F-94 aircraft was seen making an approach to the field for landing during the timeframe of the sighting. Internal notes on the record card highlight a discrepancy in the reported duration of the event, noting a conflict between the time window of 2330Z to 0030Z and the specific duration of 15 to 20 minutes. While the initial assessment suggested the object might have been a balloon, the investigators concluded that the timing did not align with any scheduled balloon launches, leaving the incident categorized as unknown.
