Me too - the connections were Steven Speilberg and Showcase Cinema!
I'm sorry - I have no faith in "they're hiding something" conspiracy theories. I've worked for the government. Government employees are big mouths - thousands of people would NEVER be able to keep something like that a secret. Somebody's going to tell their wife or their girlfriend or someone.
Besides, what possible reason would NASA have for keeping something like that a secret? They would have no reason to. On the contrary, they would have EVERY incentive to announce such a discovery in order to get more funding and more research. Keeping it secret flies in the face of simple logic.
Many of us had access to very highly classified activities, but we were just as interested about the Roswell mystery as anyone else.
You are correct, secrets are almost impossible to keep in the government more than a few short years, because people will always talk.
We all form our hypotheses about reality from our own experiences.
I understand that yours have been different from mine.
I held a high security clearance in the Navy, too. And, some relatives and friends had even higher clearances.
Certainly many folks have spoken to others about work related things in secret locations. But the ridicule, disinformation strategy works very well.
And, as numerous cases have shown, the government CAN keep incredible things secret for decades. It depends on a lot of factors, imho.
