Project 10073 Record Card and Related Correspondence

This document contains records and correspondence regarding two separate Unidentified Aerial Phenomena (UAP) sightings reported in October 1951. The first report, dated 1 October 1951, concerns an observation at Ellington AFB, Texas. The witness described a whitish-blue, 12-inch diameter object at an altitude of 400-500 feet, which appeared to emit constant rays of light similar to a glittering diamond. This incident was evaluated by the Air Technical Intelligence Center (ATIC) as the planet Venus. The second report, dated 2 October 1951, details a sighting in Columbus, Ohio, by a graduate physicist from the Battelle Memorial Institute. The witness observed a bright, circular object traveling directly west at high speed for approximately one minute. The witness, who had no aircraft experience, explicitly noted that the object did not appear to be a balloon or a parachute, and that it followed a straight-line path without changing altitude or maneuvering. Correspondence from 9 October 1951, addressed to Lt. Col. M. J. Piatnitza at Wright-Patterson Air Force Base, provides further analysis of this second sighting. The author notes that weather data from the W-P AFB Weather Station indicates that the object could not have been a weather balloon, as it would have been traveling into the wind at high altitudes, and a balloon launched at 1500 hours would have risen too high to be seen by the time of the 1800-hour sighting. The document includes sketches and technical notes regarding the object's appearance and the witness's observations, emphasizing the witness's belief that the object was of a real, physical origin rather than a visual illusion or reflection.
