Stored out in area S5 south of Groom Lake where they reverse-engineer alien space craft into Apple products.
In 1908, an alien spacecraft exploded at Tunguska, Russia;
The Roswell alien spacecraft was a rescue mission for the Tunguska crash, but it fell through a wormhole and crashed in the New Mexico desert 39 years later;
A piece of alien technology from the Roswell crash was discovered by a teenager who was working as counter help at Build-a-Burger at the time;
The teenager turned it over to the Nazi scientists of Operation Paperclip (he was placed in a government relocation program in Memphis, TN under the name Elvis Presley, where he promptly blew cover);
The Nazi scientists reverse-engineered the alien technology and developed the Internet, GMO's, fracking and chemtrail technology, which in turn sucks our precious bodily fluids from the atmosphere and provides power for the HAARP array;
The HAARP array destroyed the Twin Towers and the Pentagon on the order of George W. Bush, who personally detonated them from his secret Skull and Bones man-cave beneath the campus of UT-Austin.
There, it all makes sense, Mulder and Scully were right, The Truth Is Out There, man!
