In mid-1947, the top-secret Project Mogul operated high-altitude balloon trains from Alamogordo Army Air Field to detect Soviet nuclear tests. A balloon train carrying metallic and rubber equipment came down on a ranch near Corona, New Mexico. To protect the classified program, the Army Air Forces initially described the debris as a 'flying disc,' then quickly retracted that claim and attributed it to a conventional weather balloon.
Rancher Mac Brazel discovered unusual metallic and rubber debris on his property near Corona, New Mexico. Roswell Army Air Field personnel recovered the material, and on July 8, 1947, the Army Air Forces issued a press release announcing the recovery of a 'flying disc.' The statement generated worldwide headlines before being retracted and replaced with the weather balloon explanation, which was itself a deliberate misdirection to conceal Project Mogul.
In 1978, retired Air Force officer Jesse Marcel publicly alleged a cover-up, fueling UFO speculation that was amplified by the 1980 book The Roswell Incident. Subsequent decades saw expanding conspiracy theories involving grey aliens, crashed saucers, and government suppression of extraterrestrial evidence. Despite Air Force reports in the 1990s confirming Project Mogul as the source, the incident became a cultural phenomenon and a driver of UFO tourism in Roswell, New Mexico.
