Project 10073 Record Cards and Related Correspondence — St. Louis, Missouri, November 1957

This document collection consists of Project 10073 record cards and associated military teletype correspondence regarding UFO sightings in the St. Louis, Missouri area during November 1957. The reports detail three distinct incidents. The first, occurring on November 5, 1957, involved a report of a round, greenish-blue object with red tints that appeared larger than a star and exhibited a tumbling motion. This was observed for 50 minutes. Official analysis concluded this was the planet Venus, as an astronomical plot confirmed its location at the time of the sighting. The second and third incidents, reported on November 9 and 10, 1957, involved objects described as resembling jet aircraft or meteors. One witness reported a long, white object that appeared to burn out, while another described a long, white, low-overhead object. These sightings were investigated by the 798th ACWRON and the 20th Air Division. Military investigators, including 1/Lt James S. Prowell, noted that there were jet fighter operations in the area at the time of the sightings. The final ATIC conclusions for these reports indicate that the sightings were likely jet aircraft, specifically F-100 series, conducting test runs. The investigators emphasized that jet aircraft at night, particularly at high altitudes, can easily be mistaken for meteors. The documentation includes standard record cards, teletype messages between military units, and handwritten notes from investigators evaluating the reports. The overall assessment by ATIC was that the reports were 'skimpy' and lacked specific data, but that the available evidence pointed toward conventional aircraft rather than unidentified aerial phenomena.
