Area 51.....what's really going on there?

Secret military base, allows testing of new technology developed by military contractors. No alien UFOs (yes, aircraft that can't be identified), no aliens, just secret stuff they don't want the public (or the bad guys) to know. Since it's secret, anyone can make up a bunch of BS and support the BS since the military won't allow cameras or visitors onto the base. Anyone claiming to have worked there and seen aliens or UFOs is just milking the public for cash - plain and simple.
