Project 10073 Record Cards and Technical Information Sheets — Dayton, Ohio, October 1961

This document consists of a series of Project 10073 Record Cards and associated U.S. Air Force Technical Information Sheets documenting multiple unidentified aerial phenomena sightings reported in Dayton, Ohio, during October 1961. The reports detail observations made by civilians, including sightings on October 12, 16, 21, and 27. Witnesses described various objects, ranging from large, bright, white lights that appeared to move at high speeds and change color, to egg-shaped objects. One report specifically mentions an object that appeared to be a large star that changed colors, which investigators later concluded was likely the star Sirius. Another report describes two objects moving in a north-to-south direction, which were initially thought to be insects but were later ruled out in favor of an aircraft explanation. The investigators consistently referenced the proximity of the sightings to Wright-Patterson Air Force Base and the high volume of air traffic in the area as primary factors in their evaluations. The documentation includes detailed questionnaires completed by the witnesses, providing information on their location, the duration of the sightings, the weather conditions, and their personal observations regarding the objects' behavior, such as their speed, flight path, and lack of sound. The investigators' comments on the record cards reflect a systematic effort to categorize these events as conventional phenomena, such as aircraft, astronomical bodies, or other identifiable objects, rather than unexplained anomalies. The reports emphasize the importance of altitude, distance, and the time of day in explaining the sightings, noting that the lack of distinct outlines or noise could be accounted for by the distance and atmospheric conditions.
