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. 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 regular Janet fleet is composed of six Boeing 737s and five Beechcraft King Air turboprops. The 737s are painted white with a red stripe down the center of the fuselage. The King Airs are also white, but painted with a blue strip down the plane. For the most part, the 737s perform about twenty scheduled flights between LAS, TNX, and Groom Lake daily. The King Airs typically fly workers to and from locations in southern California like Edwards AFB and Palmdale. The King Airs also seem to operate the bulk of unscheduled flights.
The 737-200 fleet was recently phased out with the arrival of the 737-600s. All the new aircraft are ex-Air China and with the exception of N273RH and N365SR were previously operated by the now defunct China Southwest Airlines before being acquired for US Air Force operations starting in 2008. Most of the Beechcraft airplanes were sold directly to the Air Force, except for two, which had civilian owners first.
The airline is operated by the Special Projects division of EG&G (Edgerton, Germeshausen, and Grier, Inc.), whose headquarters is located in an office park south of Las Vegas' McCarren Airport. The red and white paint scheme on the 737s is probably a visual reference to EG&G’s logo, which features a three-pronged red cross. From time to time, EG&G posts Las Vegas job openings for pilots and flight attendants, all of which require “Secret” security clearances or above.
