Project 10073 Record — Dayton, Ohio, 4 January 1966

This document contains a Project 10073 record regarding a civilian sighting of an unidentified aerial object in Dayton, Ohio, on 4 January 1966. The observer, who worked in a control tower, reported seeing a grayish object heading Northeast. The object was described as being longer from side to side, making no noise, and traveling faster than a nearby jet plane that was leaving a vapor trail. The object itself left no smoke or contrails. The official conclusion reached by the Foreign Technology Division was that the object was an aircraft. The file includes correspondence from Major Hector Quintanilla, Jr., Chief of Project Blue Book, requesting further information from the witness, as well as a subsequent letter dated 26 January 1966, which identifies the object as a satellite (ECHO I) that had passed North of Cincinnati at the time of the sighting. The document also contains a separate, unrelated report regarding a sighting on 3 January 1966, which was concluded to be a meteor (Astro) associated with the Quadrantid meteor shower.
