Project Blue Book Files: 10 Declassified UFO Files
Project Blue Book was the Air Force's UFO project; its Special Report No. 14 came from the Air Technical Intelligence Center at Wright-Patterson Air Force Base on 5 May 1955. In a 1952 briefing, Capt. Edward Ruppelt said about 800 cases were on record and about 20% were good reports that allowed no conclusions. The 1952 Tremonton, Utah, film split opinion: one analysis found the images brighter than any bird, while a proposed press line called them balloons or gulls.

- DOW-UAP-PR159 — Historical Film of Reported UFOs, Utah, 1952 — A 16mm Kodachrome clip of the Tremonton lights, because nothing says ‘official UFO evidence’ like handheld cinema from 1952—grainy enough to be convincing, blurry enough to be plausible.
- CIA-UAP-015 — Project Blue Book Special Report No. 14 (Analysis of Reports of Unidentified Aerial Objects) — The CIA‑sponsored Special Report No. 14, a 1955 analytical deep‑dive that still lists 20% of cases unexplained—proof that even spies love a good mystery.
- DOW-UAP-D154 — Transcript of a Presentation by Captain Edward J. Ruppelt, 1952 — Captain Edward J. Ruppelt’s March 1952 presentation transcript, where he proudly notes 800 cases reviewed and a 20% “unexplained” rate—because why settle for ordinary when you can have a quarter of them mysterious?
- DOW-UAP-D092 — Department of the Air Force Committee to Review Project Bluebook, 1966-1967 — Minutes from the 1966 Air Force committee meeting to review Blue Book, showcasing Pentagon’s love‑hate relationship with UFOs—high‑level talk that sounds like a bureaucratic séance.
