What are some of governments' most fascinating secrets that have been revealed to the public?
Off top of my head, I say it is the lust for 16 years old.
hahah oh wow
WW2 code breaking both the nazi machine and japan normal code
in desiding major battles
hoovers FBI spying on people who were NOT a goverment threat
but far too many SNAFUs are covered up by stamping them top secret
a process that should be treason but saddly is normal procedure
Countermeasures to defeat stealth.
How to defeat the countermeasures to stealth.
Aurora [or whatever it really is].
Reagan's strategy to bankrupt the Soviets by hyping SDI.
Coupled with Saudi Arabia's agreeing to pump excess oil, in order to keep prices low, to restrict Soviet oil revenues. As well as the funding and supporting of Osama bin Laden and others fighting the Soviets in Afghanistan.
It is the covert overthrow of governments hostile to American business interests, as opposed to American security interests that I find to be the most disturbing
The Corona satellite program. A fascinating history, coupled with a bizarre and spectacular method of recovering satellite imagery - the film canisters were ejected from satellites to re-enter the atmosphere and planes would snatch the falling cannisters out of mid-air. Amazingly, they had a nearly perfect record for recovering the canisters. Just one of those jobs where I'm sure the pilots cursed the secrecy of the program - how do you make your living snatching objects falling from outer space and not brag about it?
Actually, the military's entire space history is pretty fascinating. I read an article on 'stealth' aircraft carriers once. Obviously, there's no such thing as a stealth aircraft carrier, but the article talked about the tactics the Navy uses to obscure the location of its aircraft carriers and how the game has evolved to a whole new level with the advent of reconnaissance satellites.
Nice pic here (even if I have to say it myself):
There could be stealth aircraft carriers if the Navy wasn't so dogmatic/beaurocratic. Ben Rich's book "Skunk Works" (he was the director) discusses the development of stealth and talks about the stealth ship ideas. There are stealth components on newer ships (such as the Arleigh Burke's sloped, diamond-shaped mast), but it is possible to make ships - even aircraft carriers - appear no bigger than lifeboats to radar. The navy simply isn't interested.
Anyway, the development of stealth is fascinating and I highly recommend that book. It also talks about the U-2 and SR-71.
edit: actually, the navy is working on some real stealth ship designs: http://www.lowobservable.com/Ships.htm
They're only a generation overdue.
I worked on a stealth boat for a navy,  so I know that they are already out there.
Anything that hasn't been declassified would be pretty much specualtion, unless the poster was there and is willing to talk about it.
During the early years of the cold war the military had some radical ideas about weapons delivery systems, mostly aircraft, that never went beyond the experimental stage.
When I say radical, I mean aircraft like nuclear powered bombers. These were to be replacemnts for the B 52, which is still flying 50 years later.
