Area 51: Secrets, Spies, and UFOs

Area 51 isn't just some random desert base. It's America's most classified military

facility, and the government denied its existence for decades. Back in 1955,

they built it to test the U2 spy plane, which flew so high people thought they

were seeing UFOs. That's actually where the alien conspiracy started. The CIA even admitted

they encouraged the alien stories to cover up their secret aircraft tests.

Millions of taxpayer dollars go into this place every year, and we still have

zero clue what's happening inside. Workers fly in on unmarked planes from Vegas,

sign NDAs that could land them in prison, and the perimeter is guarded by sensors and snipers.
