Project 10073 Record Card — New Cambria, Missouri, 24 November 1957

On 24 November 1957, at 1920Z, a Ground Observer Corps (GOC) supervisor named Harry Milliron observed an unidentified object over New Cambria, Missouri. The witness, who was 46 years old at the time, observed the object for approximately ten minutes using binoculars. He described the object as round, opaque, and very large. The witness reported that the object had no tail, trail, or exhaust, made no sound, and was traveling very slowly in a southerly direction. The report notes that the object was at an estimated altitude of 15,000 feet. The weather conditions at the time were reported as clear with unlimited visibility. The incident was documented on a Project 10073 record card and subsequently reported via teletype by the 798th ACWRON at Belleville Air Force Station, Illinois, to the Air Defense Command (ADC) and the Air Technical Intelligence Center (ATIC). The official evaluation of the sighting concluded that the object was a balloon, noting that while specific elevation and azimuth data were missing, the physical description and flight behavior were consistent with a balloon observation. The report includes a handwritten note stating, 'Typical GOC Report' and 'Object seen for 10 minutes with binoculars and cannot give any EEI's' (Essential Elements of Information).
