The Roswell UFO incident is an event that occurred in the summer of 1947, when an unidentified flying object crashed near Roswell, New Mexico. The incident has since become the subject of intense speculation and debate, with some believing that the object was of extraterrestrial origin. Reports of the incident
Debris found by a rancher in 1947 near Roswell, New Mexico, has become the basis for UFO conspiracy theories alleging that the United States military recovered a crashed extraterrestrial spacecraft. After metallic and rubber debris was recovered by Roswell Army Air Field personnel, the United States Army Air Forces announced possession of a "flying disc". This announcement made international headlines, but was retracted within a day. The debris was from a complex and uncrewed military balloon train consisting of linked balloons and assorted equipment, operated from the nearby Alamogordo Army Air Field as part of the top-secret Project Mogul, a program intended to detect Soviet nuclear tests. To obscure the purpose and source of the debris, the army reported that it was merely a conventional weather balloon.
