PROJECT 10073 RECORD CARD - 23 MARCH 1957

This document is a Project 10073 record card and associated technical information sheets detailing an Unidentified Aerial Phenomena sighting reported on March 23, 1957. The primary witness, Lt. Col. R.E. McDonald, a pilot stationed at Clinton County AFB, Ohio, observed a white flash of light while flying a C-46 aircraft. The object, described as ball-shaped with a reddish trail, moved from west to east on a level flight path. The witness reported that the object was visible for three to five seconds and was bright enough to illuminate the cockpit of his aircraft for two to three seconds. The report notes that there was no sound associated with the object. The investigation, conducted by Capt. Stewart F. Marrs, concluded that the sighting was likely an astronomical event, specifically a fireball meteor, based on the description, duration, flight path, and the manner in which the object faded rapidly. The report includes technical data, such as the witness's bearing estimates and weather conditions, which were noted as clear. The document also contains internal military communications, including a teletype message from the 1289th AACS Squadron, confirming the report's processing through Air Technical Intelligence Center (ATIC) channels.
