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.

Adams that I had not intended to undermine local security measures, but had merely posed an honest question, he recommended I be more prudent in the future. Here, we mustn't reproach Col. Adams too severely, because his job was to abide by the military intelligence axiom of "never underestimate a potential enem.y.n This axiom. no doubt inspired the following Eustis pol~cy, a po-licy which was probably the basis for Col. Adams's investigation: "A great part of the information sought by people who do not have the best interests of the United States at heart. is obtained from unclassi fied sources through apparently innocent requests. Any unusual request for information concerning the installation, our personnel, or other data, should be brought to the attention of the Assistant Chief of Staff, G-2."
