As far as your facts, I don't see anything wrong here. However, you seem to have over looked the Common thread that ties everything together:

The COLD WAR

While all of this was going on, the Cold War was just beginning between East and West. It was the Cold War that brought the mistrust and mutual suspicion that would Drive the suspision behind these events. At that time, the Government built a wall of secrets around itself to keep the Russians !away.

Without a doubt the cold war bumped it to Top Secret status and covered it in a protective cloak. It appeared to all be going public when the saucer crashed at Roswell, but the headlines quickly disappeared and denial started. I'm sure our military leaders were seeking to gain an edge of the Russians through technology by putting it under wraps. I also highly suspect it will STAY under wraps for the same reason.

I tend to agree with a radio talk show host who once said that if tensions between us and another nation reach a near boiling point, all we'd probably have to do is take their leader, or their UN diplomat, out west, show them what we have hidden away through reverse engineering, and advise them to wake up the next morning with a new attitude.
