Despite the fact you can't really miss it, the existence of Area 51 has never been acknowledged "officially" until recently. But the self-perpetuating hoaxes and stories arising from Area 51 has been perhaps one of the greatest propaganda successes ever from the Cold War, where some of the most advanced aircraft in history have been developed and tested right under the noses of adversaries and allies alike. It has served its purpose well, and there is no longer a need to hide behind the myth of UFOs from outer space. The now famed U-2, D-21 (drone), SR71 Blackbird, B-2 stealth bomber, F-117, F-22 Raptor stealth fighter, etc were all at first denied officially to exist, and public sightings were accepted by default as originating from "outer space" in the mainstream fury of UFO mania.

The US has been developing and testing UFOs for over fifty years in not only Area 51 (just off of Hwy 375, the Extraterrestrial Highway in Nevada), but also other remote detachments such as Edwards Air Force Base and in the city of Burbank in California. The even more secretive Area 52 (Tonopah Test Range), is believed to be the origin of aircraft and unmanned drones with increasingly stunning performance. For example, as recently as the mid-80s, when most of world was still in the dark about stealth technology, local residents saw bat-like UFOs (F-117s) flying overhead almost nightly. Quite frequently such aircraft are mistaken for "extraterrestrial" UFOs. A dramatic crash of a "UFO" was in fact reported in 2008 at Andersen Air Force base in Guam.
