Leaked video allegedly shows alien aircraft being tested at Area 51

Conspiracy theorist group SecureTeam 10 uploaded a video to YouTube of "leaked" footage of an alleged alien aircraft being tested at Area 51 in Nevada.

The video, which has racked up hundreds of thousands of views, appears to show a flying object hovering in a way that no known aircraft can currently achieve.

Light bursts forth from the flying object as it moves side to side them up and down.

In the video, Tyler Glockner, who runs the YouTube channel, calls the clip a "hidden gem" that was filmed in the 1980s or 1990s.

"It's one of the mysterious pieces in UFOlogy," Glockner said of the footage.

Area 51 has become a hot topic for extraterrestrial enthusiasts since the U.S. government did not acknowledge that it existed until 2013.

Famous aircraft such as the U-2 spy plane and the Lockheed SR-71 Blackbird were tested in the area, and some conspiracy theorists believe that is where the government does research on alien aircraft as well.
