Sighting Report — Spooner, Wisconsin, 29 March 1953

This document collection details an Unidentified Aerial Phenomenon (UAP) sighting that occurred on 29 March 1953, approximately 6.5 miles east of Spooner, Wisconsin. The report, processed by the 31st Air Division and forwarded to the Air Technical Intelligence Center (ATIC) at Wright-Patterson Air Force Base, describes a circular, aluminum-colored disc observed by four individuals who were installing a television antenna. The witnesses reported that the object appeared to be approximately half the size of the moon and was at a very high altitude. Over a duration of 15 seconds, the object reportedly traveled at a high rate of speed from south to north, reversed its direction twice, and eventually disappeared to the north. The witnesses, including the primary reporter who was a hatchery manager, had no formal training in aircraft recognition, though the primary witness noted a similar sighting in 1938. Weather conditions at the time were reported as clear with thin light cirrus clouds. The report includes standard Air Force technical information sheets, correspondence from the Emerson McMillin Observatory at The Ohio State University, and official military teletype communications. In his correspondence dated 19 May 1953, the observatory representative expressed skepticism regarding the duration of the sighting, noting that it was difficult to believe the object could have performed the described maneuvers in only 15 seconds. The case was officially classified as 'UNIDENTIFIED' and was flagged for further investigation, with a recommendation that a formal questionnaire be sent to the witness. The documentation highlights the military's systematic approach to collecting and evaluating civilian reports of aerial phenomena during the early 1950s, emphasizing the reliance on standardized reporting forms and the subsequent review by intelligence personnel.
