In July 1994, the Office of the Secretary of the Air Force concluded an exhaustive search for records in response to a General Accounting Office (GAO) inquiry of an event popularly known as the "Roswell Incident." The focus of the GAO probe, initiated at the request of New Mexico Congressman Steven Schiff, was to determine if the U.S. Air Force, or any other U.S. government agency, possessed information on the alleged crash and recovery of an extraterrestrial vehicle and its alien occupants near Roswell, N.M. in July 1947. Reports of flying saucers and alien bodies allegedly sighted in the Roswell area in 1947, have been the subject of intense domestic and international media attention. The July 1994 Air Force report concluded that the predecessor to the U.S. Air Force, the U.S. Army Air Forces, did indeed recover material near Roswell in July 1947. This 1,000-page report methodically explains that what was recovered by the Army Air Forces was not the remnants of an extraterrestrial spacecraft and its alien crew, but debris from an Army Air Forces balloon-borne research project code named MoGUL. Records located describing research carried out under the MoGUL project, most of which were never classified (and publicly available) were collected, provided to GAO, and published in one volume for ease of access for the general public. This publication contains the complete report as submitted to the Secretary of the Air Force.
