In the mid to late 1990's, the United States Air Force responded to a General Accounting Office inquiry regarding what has become known as the "Roswell Incident" with two reports explaining the Air Force's version of the events. The "Roswell Incident" refers to witness accounts of debris from an Unidentified Flying Object (UFO) and alien corpses from the alleged UFO crash near the town of Roswell, New Mexico. The second of the reports addresses the likelihood that the "alien corpses" seen in the New Mexico desert were actually anthropomorphic dummies from high-altitude parachute drops conducted with dummies from the Aero Medical Laboratory at Wright Air Development Center. Both are available here at NavyUFO.org for you to download.
