Majestic Twelve

Majestic 12 is thought to be the code name of a secret committee of scientists, military leaders, and government officials, supposedly ... all formed in 1947 by an executive order of U.S. President Harry S. Truman. The purpose was to investigate UFO activity in the aftermath of the Roswell incident, the purported crash of an alien spaceship near Roswell, New Mexico in July 1947. This alleged committee is an important part of the UFO conspiracy theory of an ongoing government cover up of UFO information.
