Project 10073 Record Card: Sighting of 4 September 1957

This document collection pertains to a UFO sighting reported on 4 September 1957 in the vicinity of Brookville, Ohio, and Spencer, Wisconsin. The primary record is a Project 10073 card documenting a civilian GOC observer's report of a stationary, blinking object in the night sky, described as red, white, and orange. The report includes multiple technical information sheets filled out by witnesses, as well as internal Air Force correspondence. The Air Force investigation, conducted by the Air Technical Intelligence Center (ATIC), concluded that the phenomenon was the Aurora Borealis, which was widely reported across the mid-western United States on that date. The file also contains later correspondence from 1959, where Major L. J. Tacker responded to a witness who had written to the Air Force two years after the event. Major Tacker dismissed the inquiry, stating that the report was too old to evaluate and that the witness was likely influenced by popular literature on flying saucers. The documentation includes internal military communications, such as a teletype from the 676th ACW Squadron, confirming that weather stations and operations centers were queried regarding the sighting. The consensus among the military evaluators was that the visual phenomena were atmospheric in nature, specifically aurora streamers, and not indicative of an unidentified aerial vehicle.
