Project 10073 Record and Related Correspondence — Tucson, Arizona, April 1967

This document contains records and correspondence related to two separate UFO sightings reported in Tucson, Arizona, in April 1967. The first incident occurred on 1 April 1967, involving a civilian witness who observed a round, orange-red object that appeared larger than a star and did not blink. The object was seen descending until it dropped below the horizon. The Air Force's Foreign Technology Division initially requested more information from the witness, and the final conclusion for this event was 'Possible (AIRCRAFT),' noting that no data existed to prove it was not an aircraft. The second incident occurred on 18 April 1967, involving a different witness who described a very bright, orange object with dark spots and a blue halo. This object was also observed for approximately 15 minutes before disappearing. The official conclusion for this second sighting was 'BALLOON (Hot Air).' Major Richard Dean of the Base Operations Branch at Davis-Monthan AFB provided investigative context, noting that numerous UFO reports in the area often correlated with the red obstruction lights on radio towers located on Mt. Lemmon, which could be visible from parts of Tucson depending on the observer's location and intervening terrain. The reports include detailed questionnaires, meteorological data, and internal Air Force message traffic regarding the investigations.
