Documents / FOIA release
This FBI file section, from 1947, gathers Army Air Forces counterintelligence reports and FBI memoranda about the summer's flying disc reports. It includes a Boise newspaper pilot's sworn statement describing a black object he filmed on 9 July 1947, interviews with a United Air Lines captain and a Hamilton Field soldier, and a Pan American crew's orange object near Boston. Other items cover the Tacoma disk fragment story, which was admitted to be false, the fatal B-25 crash at Kelso, a coded "Radio Ham" message dismissed as a hoax, and an Air Defense Command assessment that "something is really flying around."
