Well, without derailing the thread with my views on alien visitation and the possability of technology being captured, I'll just say this;
Area-51 is still very much an operational USAF base with security the likes of which makes Fort Knox look like it could broken into easily. I think it is still the home of alot of testing operations for the latest in aerospace technology. Hell, the "state-of-the-art" F-22 is already nearing it's 20th birthday since the introduction of the prototype which just makes me wonder what those test pilots over there are flying now.
I have often heard people claim that Area-51 has packed up and moved someplace else because of "pressure from sight seers" or something like that. First of all, most, if not all of these claims, can be traced right back to an article Popular Mechanics ran back in the late 90s. In it, the writer, Bob Wilson, claimed he even drove all the way up to the front gates of the base without being disturbed and that proves the base must have moved. That's all fine and good, but what isn't very widely known is that Bob Wilson was incompetent when it came to reading a map. His sensational story was all based on a visitation to a wholly different and unrelated facility that Wilson mistook for Area-51. No joke.
Secondly, there's really no "pressure" coming from sightseers. The point where the tourists can be shot on sight begins a full ten to fifteen miles from the actual perimiter of the base. And the peaks where people could actually get a glimps of the base itself had been cordoned off years ago. The base continues to do it's thing unseen and unbothered. The dozens of commuter flights and buses to and from the base is a testimate to its activity which, if anything, is even greater than it's ever been previously.
