The Air Force is warning people not to try and storm Area 51.
Hundreds of thousands of people have signed up for a Facebook group that proposed everyone rush the top secret military base in the Nevada desert this September, in an effort to unlock its alien secrets.
A joke or not, the Air Force says don't try it. A spokeswoman said that the base is an active training range for the Air Force and that it will protect America and its assets. The satirical event is scheduled for September 20.
If you are thinking about going, heads up. The perimeter of the base is constantly patrolled by armed security guards and CCTV and motion-sensor cameras are also in use – with signs around the base warning intruders could face “deadly force”.
