The origin of Area 51 name isn’t clear, although it was in use since at least 1967. The other officially confirmed name is Homely airport (KXTA), which suddenly appeared in civilian navigational databases in 2007. It is believed that the it was let out by mistake and since then Aircraft Owners and Pilots Association has issued several warnings that neither landing nor use of KXTA as a waypoint should be attempted by any unauthorized pilots. During its construction in the 1950s, it was referred as Paradise Ranch, but it was more of a stunt to attract workers than an official name tag. The other names used to describe it were Dreamland, The Ranch, Home Base and Watertown. Today, the most likely name is Air Force Flight Test Center, Detachment 3, but that was never confirmed. Another unconfirmed theory proposes the name National Classified Test Facility.
