This 1954 to 1955 file of U.S. Air Force Directorate of Intelligence correspondence gathers letters and memos about the Unidentified Flying Object Program. In one memo, the Air Force says an object that fell at Sylacauga, Alabama was identified as a meteorite at the Air Technical Intelligence Center. Donald Keyhoe questions the Office of Naval Research about the Navy's analysis of the Tremonton film, and the Navy says data are insufficient and it sees no danger. Most of the replies to the public enclose the Air Force UFO summary.

Page 4, letter dated Dec. 2, 1954, to the Chief of the Office of Naval Research, attention of Lt. Cdr. Frank Thomas... 7. Finally, I should like to have a statement of the Navy's conclusions, if available, in regard to the probable motives for the UFO operations. In the Navy's opinion, does the accumulated information on "flying saucers" or what the Air Force now terms UFOB's, constitute grounds for believing there is any attendant danger? 8. According to a source I believe reliable, the Navy is now experimenting in the field of magnetic power, for propulsion of missile and/or space vehicles. Since the Air Force publicly announced, some time ago, that it had contracted for research into all phases of magnetics, it seems logical to believe the Navy is carrying on similar research. Will the Navy verify this? I should welcome any additional information which you feel is appropriate, in regard to the Navy's position on Unidentified Flying Objects.
