Do UFO files exist?

Yes. Publicly released UFO files exist, including government reports, correspondence, photographs, and archival records. Their existence shows that sightings were recorded or investigated; it does not prove what was seen or where it came from. [1]

For example, the National Archives of Australia released a 1971 review of the U.S. Air Force’s Project Blue Book. [2] A separate Project Blue Book file documents the investigation of a film shot near Tremonton, Utah, on July 2, 1952. [3] The Air Force examined whether the filmed objects could have been pillow balloons, and the file includes example images supplied by General Mills. [6]

Other records include Project Blue Book correspondence from 1955 and a U.S. Air Force committee’s review of the program in 1966–1967. [5] [4] These files document investigations and assessments, but they do not establish that any particular sighting involved extraterrestrial visitors; what caused some reported sightings remains unknown.
