Project 10073 Record Cards and Technical Information Sheets — Dayton, Ohio, October 1958

This document contains a series of Project 10073 record cards and U.S. Air Force Technical Information Sheets documenting multiple unidentified aerial phenomena sightings reported in Dayton, Ohio, during October 1958. The reports detail three distinct incidents occurring on October 14, 19, and 21. Witnesses, including civilians and personnel associated with local industry, described various objects, ranging from blue-green flame-like objects to white, L-shaped streaks of smoke. One witness, a 35-year-old male, described a blue-green object that appeared as a flame, changed brightness, and turned red before disappearing. Another report from October 21 describes a white, L-shaped trail of smoke that appeared to fade away. The Air Technical Intelligence Center (ATIC) conducted an investigation into these reports, contacting various agencies including Patterson Field Operations, Wright Field Operations, CAA Control, and the U.S. Weather Service. The investigation concluded that the sightings were likely attributable to conventional phenomena. Specifically, the official assessment for the October 21 sighting was that the evidence pointed to a condensation trail left by a jet aircraft flying at 40,000 feet. The reports include detailed questionnaires completed by the witnesses, covering aspects such as the time of day, weather conditions, the witness's location, and their personal observations of the objects' behavior, color, and sound. The documentation reflects the standard procedure for the Air Force to collect and evaluate civilian reports of UAP during this period, emphasizing the systematic verification of flight operations and meteorological data to rule out conventional explanations.
