HALF a million people have signed up to “storm” a U.S. military base that conspiracy theorists say holds alien technologies.

The event is called “Storm Area 51: They Can’t Stop All Of Us” and says, “We will all meet up at the Area 51 Alien Center tourist attraction and coordinate our entry.”

The event, set for Sept. 20, is likely a joke. Its creator is best-known for posting memes and streaming content on Twitch, a live streaming platform for gamers, according to comicbook.com.

According to U.S. media, the Air Force is aware of the Facebook post but is not commenting further.

Area 51 is about 150 miles from Las Vegas, it is not open to the public and is under 24-hour surveillance.

The remote 4,000-square-mile patch of desert was first used for the development of U2 spy planes in the 1950s.

That program finished after the U2 was put into service around 1956 and the base has since been used for testing other military aircraft.

But conspiracy theorists say the site has also been used to store remains of crashed UFOs and other alien technologies.

The U.S. Government’s official line is that what happens at Area 51 is classified for the purpose of national security.

But that and the fact that they only acknowledged the base’s existence in 2013 has only fueled the speculation.

Peter Merlin, a U.S. aerospace historian who has written extensively about Area 51, told NBC News that the facility is “strictly a place for testing and evaluating aircraft and associated weapons systems.”

Will the public storm Area 51 and put an end to all the speculation about whether our planet has been visited by aliens? Probably not — but we’ll have to wait two more months to find out.
