The Coyame UFO incident was a reported mid-air collision between a UFO and a small airplane said to have taken place on August 25, 1974 near the town of Coyame, Chihuahua, close to the U.S.-Mexico border. Some conspiracy theorists believe the UFO was retrieved by a United States government rapid response team assembled by military and intelligence agencies.
On 24 August 1974, a U.S. air defense radar detected an unknown object in the Gulf of Mexico, traveling at some 4,000 km/hr and headed towards Corpus Christi, Texas. Suddenly the object changed direction and headed towards Coyame, Chihuahua, Mexico. At approximately the same time a small airplane took off from El Paso, Texas, headed towards Mexico City. The U.S. radar detected both, the UFO and the small plane, and monitored both for a while until their signals disappered simultaneously and at the same location over Mexico.
