UFO Sighting Report — Tucson, Arizona, 30 May 1965

On May 30, 1965, at 0305Z, a civilian witness in Tucson, Arizona, reported observing a round, white, flashing light moving very fast from the northwest to the southeast. The witness, identified as a geologist, observed the object for approximately 15 seconds from his backyard. A second witness, TSGT Dan D. Harshman of the Base Communications Office at Davis-Monthan AFB, reported observing a similar white light with a small red flashing light passing over his house from the northwest to the southeast for 5 to 6 seconds. Both witnesses noted the object disappeared behind thin clouds. The report was filed by Major George C. Grimsley of the 12th Strategic Aerospace Division. Initial investigations by the Air Force could not identify any known aircraft in the flight path at the time of the sighting. Attempts to verify the sighting with the Kitt Peak Observatory were unsuccessful. The official conclusion reached by investigators was that the object was likely an aircraft, specifically two F4C aircraft, though the report also notes a strong possibility that the object could have been a fast, high-flying aircraft or a meteorite. No physical evidence was recovered.
