The Air Force facility commonly known as Area 51, located within the Nevada Test and Training Range, has captured the imagination of both conspiracy theorists and Hollywood for decades. The top-secret military base (which is still operational) is surrounded by barren desert, and the secrecy surrounding its Cold War-era stealth aircraft testing led to rumors of UFOs and aliens, wild government experiments and even a staged moon landing on the premises. Curious civilians can explore the area around the base, which has become a bizarre tourist destination, although they aren’t permitted inside.
