Project 10073 Record Cards and Related Correspondence — Tampa, Florida, December 1957

This document contains Project 10073 record cards and associated military teletype communications regarding two separate UFO sightings reported in Tampa, Florida, in December 1957. The first incident, occurring on 3 December 1957, involved a witness describing an egg-shaped object with white and green lights, approximately 250 feet long, which hovered and exhibited a wavering flight path. Military evaluators noted that the description had characteristics of an aircraft and suggested the sound of motors might have originated from another source, ultimately concluding the observers were influenced by publicity surrounding the Levelland, Texas, sightings. The second incident, reported on 4 December 1957, involved a witness describing a doughnut-shaped object with a plexiglass dome, three occupants wearing clear plastic helmets, and jet engines. This object was reported to have hovered at 75 to 100 feet before rising sharply. Military investigators dismissed this report as a potential hoax, suggesting it was either a helicopter observed under poor conditions or a flare, with one investigator explicitly stating their belief that the object was a 'figment of his imagination.' The documents include technical details such as weather conditions, flight paths, and physical descriptions, alongside internal military correspondence from the 660th ACWRON at MacDill Air Force Base, which processed these reports for the Air Technical Intelligence Center.
