Unidentified Aerial Phenomena Sighting Report — Union Lake, Michigan, 31 October 1953

This document details a UFO sighting reported by a civilian, identified as an Ensign in the US Naval Reserve and a licensed aircraft pilot, occurring on 1 November 1953 near Union Lake, Michigan. The report was initially relayed to the 4602D AISS at Selfridge AFB by an FBI agent named Howard on 3 November 1953. According to the witness, the object was observed for approximately 66 seconds at an estimated altitude of 7,000 to 10,000 feet. The witness described the object as a 'bluish-green haze' with no discernible material body. The object reportedly circled the city six times, with each orbit taking 11 seconds, before departing at high speed in an easterly direction. The witness, whose wife also verified the sighting, was adamant that the object was not a reflection. Despite the witness's credentials as a pilot, the official conclusion reached by the Air Technical Intelligence Center was 'INSUFFICIENT DATA.' Subsequent attempts to follow up with the witness proved unsuccessful; a questionnaire mailed to the address provided was returned by the postal service with the notation 'No such Post Office in State named.' The document also includes broader lists of sightings from October and November 1953, indicating the systematic tracking of such reports by the Air Force during this period, as well as a separate report regarding radar observations in the Indian Ocean by a Danish merchant vessel, which serves as a point of comparison for radar-related data collection.
