Project 10073 Record Card — Xenia, Ohio, 9 June 1963

On 9 June 1963, at approximately 2210 local time, an observer in the Lanewood Housing Development on the west edge of Xenia, Ohio, reported a series of blue flashes in the night sky. The witness, who was lying on a chaise lounge in their backyard, described the phenomenon as a series of 15 to 20 flashes, each similar to a flashbulb, occurring at intervals of approximately three seconds. The flashes were observed moving from a position directly overhead toward the right extremity of the horizon, which the witness identified as North, over a duration of 45 to 60 seconds. The witness noted that the flashes were evenly spaced, silent, and moved at a speed they characterized as 'phenomenal.' The sky was clear enough for stars to be visible, with only scattered clouds present. The witness explicitly stated that they did not believe the object was a meteor or an aircraft due to the bright blue color. Following the report, an investigation was conducted by checking with Wright-Patterson (WP) Operations. The investigation revealed that a T-33 aircraft from Minneapolis, with its home base at Maxwell, was in the area at 2228 (0328Z) and was over Xenia at the time of the sighting, performing a normal landing pattern. The official conclusion reached by the investigating agency was that the T-33 aircraft was the cause of the report, noting that the witness did not observe any other object.
