The top secret US airline that flies unmarked planes into Area 51 is hiring cabin crew
'Janet airlines' flies US government workers from Las Vegas to the mysterious Area 51 in Nevada
REMAINING calm in stressful situations, dealing with tricky customers and long hours in the sky.
Flight attendants work hard - but a new airline job ad expects even more of hopeful applicants.
"Janet airlines", which flies US government workers from Las Vegas to the mysterious Area 51 in Nevada is looking for cabin crew who qualify for "top secret government security clearance".
Shrouded by mystery, the airline's fleet consists of unbranded planes which are operated by the US Air Force.
And in a job advertisement posted on the website of private defence contractor states that candidates must be able to deal with unusual incidents like hijackings or bomb threats.
As well all of the duties expected of regular cabin crew such as safety demonstrations, cleaning and emergency procedure; applicants must keep quiet about where they're going and what they're doing.
Janet airlines wasn't named after a mysterious woman - the name is said to stand for "Just Another Non-Existent Terminal", but other than that very little is known about it.
Flight tracking radar shows some of the flights - with call signs starting XXX - making the 45-minute journey to the nuclear facility at Tonopah, which has been the focus of many conspiracy theories.
Other brief flights go to an unspecified destination nearby - believed to be the Area 51 facility famous with alien hunters.
The highly classified site at Groom Lake is believed to be used to test experimental aircraft and "black projects" weapons systems.
Its existence was only acknowledged publicly for the first time in 2005.
Conspiracy theorists believe the top-secret military base contains the remains of an alien spaceship that crashed in the 1940s.
Nobody who flies on the special Janet flights is allowed to reveal where they are going or what their job is.
Some conspiracy theorists believe the area holds the remains of a crashed alien spaceship, but an extra-terrestrial expert who used to investigate UFOs for the British Ministry of Defence believes there is little to the rumours.
