Area 51?

Here's an interesting new article by Bill Sweetman about Area 51. Its good to see that Bill's still on the hunt for the elusive Aurora. Its obvious that there has been a fair amount of activity there in the 90s and 2000s, besides Tacit Blue,the Polecat and the Bird of Prey. We still don't know anything about the elusive YF-24 and YF-113G, and there are rumors of a FB-23 prototype, and/or a "Switchblade" fighter. Its interesting that Sweetman thinks that development could be continuing on the A-12, abandonded in 1991 with the $4 Billion prototypes never seen.
