I've read and listened many different things on this subject and I've come to the conclusion that there was something going on with this entire matter.

What I find interesting is how right after WWII was when we started seeing the first UFO's over America. I've watched enough video now to have a pretty good idea that the Nazi's were messing around with anti-gravitational devices where mercury was placed in some sort of container and vibrated to very high frequencies using electricity. It sounds rather far fetched but it's pretty coincidental to see how right after WWII our space and defense forces and craft seemed to take a huge leap forward in progress.
