Documents / FOIA release
This Federal Bureau of Investigation file section collects 1949 and 1952 memoranda and public letters about flying saucers. Letters from citizens offering theories were acknowledged and forwarded to the Air Force, and Hoover passed along a report of objects over Thessalon Lake, Ontario, along with an anonymous German letter about a V-weapon disc. An Air Intelligence briefing said research had reached no satisfactory conclusion. Memos also trace how the negatives of a 1947 Phoenix disc photograph were handed to Air Force Intelligence.
