Area 51 - Although it cannot be proven, there exists a lot of evidence pointing to the airline's transportation of personnel to the government's top secret military base, Area 51.

Area 51 - The base, located in Nevada, is a popular location for conspiracy theories surrounding US government activities. Many people are convinced that the government hides operations having to do with extraterrestrial life, including studying crashed UFOs, meeting with extraterrestrials, and manufacturing alien technology.

Area 51 - The US government has provided minimal information about Area 51, aside from the fact that it's highly classified. The Janet aircraft that supposedly flies there turns off tracking and communication transponders when passing through Area 51 airspace.

Area 51 - The airspace, Airspace 4808 North, is one of the most highly protected in the world.

Area 51 -

Military fighter jets patrol the airspace and are authorized to shoot down any intruders. However, Janet aircrafts pass in and out of the airspace without incident.

Call signs - After take off, the planes communicate with McCarran Departure Control using specific call signs. Once they pass through Area 51 airspace, they allegedly switch to a different frequency and change their call signs.

Other destinations - It is speculated that the airline flies to Area 51 due to the fact that it also flies to other destinations in which it doesn't turn off its transponders.

© iStock

Other destinations - The majority of the destinations are located around southern Nevada, but others are located in New York, New Mexico, and California, among others.

Other destinations -

Some of these destinations include the Naval Air Weapons Station at China Lake (pictured), Air Force Plant 42, and Edwards Air Force Base.

Travelers - Popular Mechanics reports that the airline flies anywhere from hundreds to thousands of travelers every day. Though passengers are dressed casually, they all travel to military and government facilities around the country.

Mixed signals - Although the airline is top secret and the activities of passengers are generally unknown, it is possible to see the planes when traveling through Las Vegas' airport.

Maintenance - It is also possible to spot an aircraft in Atlanta, as they are serviced at Delta Air Lines’ TechOps maintenance facility.

© Shutterstock

Original roots - All of Janet's Boeing 737-600 aircrafts originally belonged to Air China's fleet and were bought secondhand.

Only incident -

The airline has only suffered one crash. In 2004, an aircraft crashed as it approached Tonopah Test Range after the pilot had a heart attack. Five other people died.

The mystery remains -

You may be able to see Janet's planes at the airport, but most of its destinations and passenger operations remain a mystery to the general public. Do you have any theories about what the government is up to?
