Secret Janet flights to Area 51

Janet is the de facto name for a small fleet of passenger aircraft operated by defense contractor EG&G. Their aircraft currently serve mostly the Nevada Test Site (most notably Area 51) from their terminal at Las Vegas’ McCarran International Airport, and until the early 1990s also flew regular flights from Bob Hope Airport in Burbank, California.
The origin of the word "Janet" is obscure and, while it is used as a radio callsign, it is not known whether the name is an official name, code word, or acronym. The name Janet is often suggested to stand for ‘Just Another Non Existent Terminal’, referring to the terminal at Las Vegas’ McCarran Airport. Under military approach control approaching Area 51, the callsign changes from Janet to one of many code names. Flight tracking website FlightAware shows WWW as being the airlines’ ICAO identifier.
