Project 10073 Record Card and Associated Correspondence — Englewood, Colorado, September 1960

This document collection details a UFO sighting reported on September 2, 1960, in Englewood, Colorado. The primary witness, a civilian accompanied by his wife and brother, observed a white light that appeared to stop in flight and change direction radically. The object was reported to have appeared in the northwest, passed overhead at approximately 3,000 feet, and disappeared in the east over a duration of seven minutes. The report was processed under Project 10073. Following the initial report, the Aerospace Technical Intelligence Center (ATIC) requested further clarification from Lowry Air Force Base regarding the object's elevation, azimuth, and flight path, as well as a check for any aircraft or balloons in the area. The subsequent investigation by the Airdrome officer at Lowry AFB concluded that the sighting was likely an aircraft. Specifically, it was determined that a T-33 aircraft was landing at Lowry AFB at the time of the observation. The officer noted that the aircraft's landing pattern and the 45-degree approach to the initial point would cause the landing lights to appear to stop and move erratically from the observer's perspective. Furthermore, it was noted that the observer had reported similar sightings of aircraft landing lights on previous occasions. The documentation includes the original record card, internal military message traffic between Lowry AFB, the Aerospace Technical Intelligence Center, and other commands, and a final summary of the findings.
