U.S. Air Force warning individuals about internet joke

The U.S. Air Force has warned people against participating in an internet joke suggesting a large crowd of people “storm Area 51,” the top-secret Cold War test site in the Nevada desert.

A prank event on Facebook that’s attracted more than 1 million interested people suggests that a mass of people attempt to run into the mysterious site at 3 a.m. on Sept. 20^th.

Nellis Air Force Base said in a statement that the Air Force is aware of the Facebook posting and says “any attempt to illegally access the area is highly discouraged.”
