This Department of War release reproduces Project Blue Book records on the Tremonton, Utah film of 2 July 1952. In them, Navy Chief Photographer Delbert C. Newhouse explains how he filmed a group of bright objects near Tremonton. ATIC memos and a December 1952 travel report record Navy and General Mills balloon specialists judging that the objects closely resembled pillow balloons. A January 1953 memorandum discusses publicly releasing the film. The file also includes unrelated sighting reports from Phoenix and Massachusetts, plus material about Donald Keyhoe.
