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.
From the source:Release of 2026-07-10 Incident: 1955, Various. This file contains correspondence relating to Project Blue Book, a 1952-1969 U.S. Air Force program to investigate the nature and origin of unidentified flying objects (UFO).

## [2] The fact sheet, at the bottom of page 3, states: "The Air Force would like to state that no evidence has been received which would tend to indicate that the United States is being observed by machines from outer space or a foreign government." In sharp contrast to this, the Air Force press release of August 1952, based on the minutes of your press conference at the Pentagon on July 29, 1952, stated: "The Air Force has stated in the past, and reaffirms at the present time, that these unidentified aerial phenomena are not a secret weapon, missile, or aircraft, developed by the United States. None of the three military departments nor any other agency in the government is conducting experiments, classified or otherwise, with flying objects which could be a basis for the reported phenomena. As far as is known there is nothing in them that is associated with material or vehicles that are directed against the United States, from another country or from other planets." ## My question to you now is: What is the present official position of the U.S. Air Force on the question of whether or not "flying saucers" are,and have been in many of the important cases, merely secret aircraft, missiles, and weapons, under development or operational use by the United States Government and its agencies? It is obvious,from a comparison of the two Air Force statements quoted above on this page, that the Air Force no longer denies that flying saucers are American devices. I would like to get from you, if possible, an explicit statement to this effect, rather than relying on the implication contained in the omitted sentences. (It is hardly necessary to remind you that the photograph on page 163 of OPNAV P-51-110, Oct.1, 1952, gives the direct lie to the Air Force press release of August 1952, quoted above. The blame for this prevarication attaches to the officer who wrote the press release, since you yourself very skilfully avoided any direct statements at that press conference. Your statement "We have nothing that has no mass and unlimited power!" is a classic which deserves preservation in the archives.) I would very much appreciate receiving whatever answer you care to make to the two questions propounded in this letter. It is my belief that nowhere but in the Office of the Director of Intelligence is there a person who has the cognizance to answer these questions, and I respectfully request that the answer come from your office. Sincerely yours, dear,avidian Dr. Leon Davidson
