This section of the Federal Bureau of Investigation's flying saucer file 62-HQ-83894 holds FBI correspondence from 1957 to 1966. It includes a November 1957 memo saying Air Force Intelligence found the post-Sputnik sightings nonauthentic, and a Havana report of a hat-shaped disc over Matahambre, Cuba. It also has inquiries into Robert T. Stone's Inter Continental Aerial Research Foundation, a Torrington, Connecticut sighting referral, and replies to members of the public. The replies say UFOs are not within FBI jurisdiction and refer writers to the Air Force.
