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.

The lights are somewhat like a Jan + can be seen as an outpost as Equator this is my opinion that flying stars are electrical in nature. Small clouds Currents out a space (small clouds) and causing it to glow—this cloud being charged electrically and a magnetic; polarity being same as the intercepting star can never be one. ac 9-452 202
