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.
