UFO Observation Report — Commerce City, Colorado, May 23, 1967

This document contains a U.S. Air Force sighting report regarding an unidentified aerial phenomenon observed on May 22, 1967, in Commerce City, Colorado. Two witnesses, a 23-year-old male and a 45-year-old female, reported observing a round, metallic object that resembled a tuna can with a flat top and bottom. The object was described as silver and reflective, appearing to stand still for approximately 15 minutes before moving erratically and eventually rising straight up until it disappeared from view. The witnesses reported no sound. As the evening progressed, the object's appearance changed; it was described as turning a 'very fiery orange color' and appearing to have two lights, similar to a landing plane at night. The witnesses attempted to verify the object with local military and aviation facilities, including Lowry AFB, Stapleton International Airport, and Buckley Naval Base, but were informed that no radar contact was detected and no weather balloons were known to be in the area. Despite this, the witnesses later expressed a belief that the object might have been a weather balloon, noting that a local television station had reported a large weather balloon in the area at 10:00 P.M. The official conclusion recorded by the Air Force was 'Possible (BALLOON)'. The file includes correspondence from the Foreign Technology Division requesting further information from the witnesses via FTD Form 164, as well as internal teletype messages summarizing the sighting details.
