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

This document contains a series of Project 10073 Record Cards and associated U.S. Air Force Technical Information Sheets documenting three separate unidentified aerial phenomena sightings reported in Dayton, Ohio, during November 1961. The first incident, occurring on November 2, 1961, involved witnesses observing a light circling the Dayton area in a clockwise direction. Air Force investigators concluded that the light was likely from a T-33 aircraft performing landing patterns, noting that the aircraft's landing lights could appear as a single light at a distance. The second incident, reported on November 11, 1961, involved a stationary, fluctuating red and green object. This was evaluated as the star Sirius, with the perceived motion attributed to autokinesis and the appearance to scintillation. The third incident, reported on November 12, 1961, described a bright, starlike object moving in the sky. This was identified as the Echo I satellite, with the witness's report of direction and timing conforming to the satellite's known passage. The documents include detailed questionnaires completed by the witnesses, providing information on their location, the duration of the sightings, and their observations of the objects' appearance and behavior. The reports consistently indicate that the witnesses were civilians and that no photographic or radar evidence was obtained. The official conclusions for all three cases were that the phenomena were conventional, identifiable objects or celestial bodies.
