Documents / FOIA release
This Federal Bureau of Investigation file section collects 1947 records on flying disc reports, including field office memoranda from Butte, Seattle, Salt Lake City and San Francisco on sightings in Washington, Montana, Utah and Idaho. Several were attributed to burnt paper or weather balloons, and Wright Field judged debris from a Danford, Illinois farm a hoax unconnected to Project Mogul. After the Army Air Forces described FBI work as chasing "ash can covers, toilet seats and whatnot," the Bureau discontinued its flying disc investigations and referred reports to the Air Forces.

In short, I'd like to have you continue to keep in contact with me, and relay to me anything further you learn. In turn, I'll give you the whole story, which I'm just about ready to break (not in the newspapers). And if it was as dangerous as you seem to suspect, I'm afraid I'd have been a corpse long ago! But, and this is all you need remember, those disks are not red corpuscles in your eyestall, and they are not something we can forget about with an ostrich in the sand attitude. We've got to solve them, public hysteria or no. As for that hysteria, if laughing is hysteria, that's all the hysteria I've noticed: You know your business, and you handled it like a major. But I'm hoping you do the easy part now and get that report on paper. A chook for your June 24 article is going out to you. Sincerely yours, 67c
