RARE pictures show inside Area 51 and reveal that a mysterious giant hangar has suddenly vanished.
The images were captured by private pilot Gabe Zeifman, who flew along the border of the base after receiving permission to pass through the highly restricted airspace surrounding it.
It is the third time Zeifman has been able to fly so close to the base, a highly classified Air Force facility rumored to house aliens and UFOs.
Among the fascinating images he has captured are before and after shots appearing to show the disappearance of a mysterious hangar in one part of the base.
In one photo taken in April, the hanger appears to be under construction, but by the time of another photo taken in July, it has vanished.
The reason for the change is not known, but it is possible the building was only ever a temporary structure.
The pictures also show fresh angles of the Groom Lake area of the Nevada facility, a salt flat located next to the airfield.
The Air Force facility has long been the subject of rumors and extraterrestrial conspiracy theories due to the highly-classified nature of the base.
Details about what goes on there are not publicly known.
Zeifman, who is an air traffic controller and has been flying since he was a teen, had to ask special permission to cross through the restricted Area 51 airspace, according to Mystery Wire.
He records his flights with a GoPro camera, and can be heard in the footage asking for permission to cross into the space.
The pilot told Mystery Wire that he flies along a truly restricted border that he must be immensely careful not to cross.
He said a pilot who crosses the restriction line would end up in quite a bit of trouble, though he assured the publication that he wouldn’t expect anything «dramatic like they’re going to shoot you down.»
In an April interview about the first time he flew over the airspace, Zeifman told Mystery Wire that he didn’t really see any suspicious activity, but it was cool to see the area that there is so much speculation about.
