Project 10073 Record Cards — Dayton, Ohio, March 1963

This document contains two Project 10073 record cards documenting sightings of unidentified aerial phenomena in Dayton, Ohio, in March 1963. The first incident occurred on 24 March 1963 at 2030 local time. A military witness, identified as L/Col Holoviak, reported a bright object moving from west to east at a high rate of speed. The object was in sight for one to two minutes. Subsequent contact with the witness suggested the object was the ECHO I satellite, which passed south of Dayton at 2027 moving northeast at an estimated elevation of 78 degrees. The second incident occurred on 31 March 1963 at 2000 local time. A civilian witness reported a starlike object at dusk that flashed or flickered and appeared solid. The object was observed in the northeast. This case was also evaluated as the ECHO I satellite, which was noted to be over Dayton north of the city at 1954 with an elevation of 64 degrees. The file includes standard U.S. Air Force technical information sheets for reporting such events, though most of the questionnaire fields remain blank in the provided scans.
