A memo sent in 1950, with the subject line "flying saucers - information concerning", clearly states how an investigator for the United States Air Force (USAF) confirmed that 3 "flying saucers" about 50 feet wide were recovered in New Mexico and that each one contained three aliens that were about three feet tall dressed in a metalic type cloth.
According to the informant, who was not named, the flying saucers were found because of extremely high powered radar systems that were set up in the area. This radar is what is believed to have caused the UFOs to crash.
Using the freedom of information act in the U.S. we were able to obtain many documents from different branches of the Government and the military. Some of these declassifed files show interesting facts and research about aliens, flying saucers, and UFOs.
