Project 10073 Record Cards and Related Correspondence — December 1957

This document collection contains a series of Project 10073 record cards and associated disposition forms documenting Unidentified Aerial Phenomena (UAP) sightings reported in Dayton, Ohio, during December 1957. The reports detail four distinct incidents occurring on December 4, 14, 21, and 22. The sightings involved various descriptions, including a bright silver object moving from North to South-Southwest, a flashing star in the Southeast, a bright blue-white object resembling a shooting star, and a bluish-tinted circular object that appeared to change shape toward a chevron. The documentation includes technical information sheets completed by witnesses, which provide details on their location, the duration of the sightings, and their observations of the sky. Investigating officers, including Major T.J. Connair, Jr., processed these reports and cross-referenced them with operational data and astronomical charts. The official conclusions for these events were consistently identified as conventional phenomena: the December 4th sighting was attributed to aircraft in the area, the December 14th and 22nd sightings were identified as the planet Venus, and the December 21st sighting was classified as a meteor. The records reflect the standard procedure of the Air Technical Intelligence Center (ATIC) in evaluating civilian reports against known flight operations and celestial positions. The documents highlight the high volume of reports received during this period, with some witnesses noting the brightness of Venus and others observing meteoric activity as the Earth passed through meteor showers. The files include internal correspondence between AFCIN units, confirming that the reports were investigated and that witnesses were informed of the likely nature of their observations.
