Hi Jimmy70,
I think the game plan was to keep Area 51 secret as long as they could. The people who are behind the scenes planning how they are going to keep things quite always have a backup plan. As soon as information started leaking out about area 51. There is no doubt in my mind that there was another location already established. With all of the training that I received in the AF, I know that my gut tells me, that people were sworn to secrecy for a reason and the best way to keep that person from telling the secret is to make them understand the consequences of that secret getting out. It was a long time before we even knew about the SR-71. By the time it went public, there was a newer faster version working behind the scenes.
There is no telling what capabilities we have now, and at some time in the future we will learn what we now do not know. It is very hard to fathom how we could hide a technology that could change the world. My guess is that once that technology is released, then it's power can not be controlled. I believe that this power is so great that we must be willing to think differently as a world in order to evolve to a point that we do not want to hurt other people. I think that is the hardest part.
