The aircraft was declared operational in 1983 and Clancy's book "Red Storm Rising" which debuted the F-19 with all the attributes of the F-117 was published in 1986. He had excellent contacts throughout DOD. DOD acknowledged the program in 1988, but virtually nothing was known publicly about it until the Gulf War in 1990.
I consider the conspiracy nuts pandering 911 nonsense as some of the worst of the worst. Patriotic servicemen have no problem protecting the military and intelligence secrets of this country. But hiding the participation of hundreds - perhaps thousands of co-conspirators in something like a 911 or the Apollo landings are the realm of absolute fantasy.
I had left out Apollo since I feel it’s in a different league from 9/11 but it does have a few similarities as far as difficulty maintaining the conspiracy would have.
11 of the 12 men who walked on the moon had military backgrounds. Eleven had been Boy Scouts with two being Eagle Scouts. Not a group for which lying would be natural.
Of course, honorable men can lie for a noble cause but was this cause noble enough? Perhaps some bigwig comes and says, “we need to fake a moon landing in order to beat the russkies and win the Cold War.” Okay, let’s say they all agree to it to save America from communism and that’s their sacrifice, a little honor traded for victory.
Fast forward to 1992 and the Cold War ends. Somehow, miraculously, everyone involved in Apollo, from the scientists to the astronauts, to the key grip on the set where they filmed it, had kept their mouths closed and even tricked the Russians into acknowledging that the moon landing was real.
Why keep it up at that point? Surely after all this time someone would spill the beans. Four of the twelve astronauts are still alive today. There have been no death bed confessions, no tell all cash grabs, no leaks in a catholic confession booth.
And this is not 9/11 we’re talking about. Nobody involved will face a tribunal for mass murder. Yet everyone involved in Apollo, to a man, from the top to the bottom, is proud to have been part of it and the Russians, who had the best motive (then and now) and the smarts to disprove an American moon landing acknowledge it, to this day!
It just doesn’t work on any level.
