U.S. Air Force Technical Information Sheet - Sighting Report 15 October 1953

This document is a U.S. Air Force Technical Information Sheet detailing a sighting of an unidentified aerial phenomenon reported by an Aero Research Engineer at WADC. The incident occurred on October 15, 1953, at 18:15 in Dayton, Ohio. The witness, who was driving a car at the time, observed a single object for approximately 3 to 4 seconds. The object was described as round to teardrop-shaped and bluish-green in color. The witness noted that the object appeared at a 45-degree elevation to the East and disappeared just above the horizon in the same direction. The witness reported no sound associated with the object but indicated that it did flicker, throb, or pulsate. At the time of the sighting, the weather was clear and dry with a slight breeze. The witness was driving East at 20 miles per hour when the object was spotted. The report includes sketches provided by the witness showing the object's movement during a dive and after a pull-out. The official conclusion reached in the document is that the object was most likely a fireball of exceptional size and brilliance. The report was completed by the witness on December 17, 1958, several years after the initial observation.
