2 - 13: Area 51 Revealed

On October 26, 1994, the U.S. government made their first official acknowledgement of Area 51. Six months later, nearly 4,000 acres of previously public land surrounding the base were closed. Now, over a decade later, satellite photos reveal new buildings, towers and runways finishing construction. Secret flights with blacked-out windows bring passengers from Las Vegas.
