U.S. Department of War · 1955 · 220 pages · text by GLM-OCR

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.
