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.

ostinate their elevation could have varied a thousand feet one day or another up or down, but they were pretty much on the horizon to me which would therefore they were. I was. They flirted in many ways. I have observed people so fly at them diagonal chords like lines as if they were linked together. They seemed to hold a definite direction but rather swerved in and out of the high mountain peaks. Their speed at the time did not impress me particularly, because I thought that the access had been made right along their path was the fact that I could not see them, and I assure that any pilot would justify more than a second look at such a place. I observed them quite plainly, and I estimate my distance from them, which is all only a right angle, to be between them to the fifty-five miles. I know they must be very large to observe their appearance at that distance, even on as clear a day as it was that Tuesday. In fact, I could parade a souvenir or coaling tool I had in my pocket with them - holding it up on the and holding it up on the DC-4 thus I could observe quite a distance to my left = and they seemed a little less than the DC-4; but I should judge their open would have been as wide as the furthest distance on one side of the fuselage of the DC-4. The more I observed these objects, the more precise I became, as I encountered them. All objects, including the one passing another high snow-covered ridge in between it. Under and Mr. Adams, and as the first one was passing the south crest of this ridge the last one was entering the northern crest of the ridge. COPY
