Your answer is not be all, end all, of it. Like Guatemalans being deliberately infected with nasty illnesses after WW2 to so science experiments on. That was covered up for many years until recently.
Yes, that's germ warfare experiments. We've known about crazy things governments have been doing for years. People have had odd ideas, but they've all come out over the years.
And if it's nothing at all...why is it with things like the Roswell incident where witnesses said they were threatened to keep quiet, and that their children were threatened (which is an all time low)?
Because the Roswell incident was debris from Project Mogul, a top secret US government program to detect soundwaves from Soviet experiments. Given how paranoid about the red threat the US was then, it's no wonder that they did things like that to keep it secret.
Or that kid in UK who tapped into US top secret files (with a dial up connection, as well) and the US wants to throw the book to this kid, and making the UK angry against us....on UFO info....if, as you say, there's nothing there, why would their be a big stink on a kid trying to find the truth, or why the files concerning UFO's be so hush hush?
Are you talking about Gary McKinnon? He was a guy with aspergers who supposedly did it while high on cannabis. I'd hardly call that a reliable witness. He was lucky enough to find a backdoor, and then left a stupid message on their systems which lead them back to him. Governments get angry about that kind of thing, no UFOs needed.
Or why so much hush hush on the Kennedy killing and so on if only one man did it? See, it seems.
You mean the Kennedy assassination that's been examined for years by not just governments but independent ballistics experts who've found that there's nothing weird about it?
You need to give me proof it's all a fairy tale. You see, folks like yourself always want such proof from us that can pass even a white glove test, but you have to, in turn give proof that equals it.
Given how excitable, suggestible and prone to irrationality people can be, that's pretty much all the proof we need. People see weird things, and then embellish the story. They see a Chinese lantern in the sky from the distance, and think it's a giant spaceship. They see Venus, and think it's a floating disk. They see an unusual plane they've never seen before, and they think it's a ship from another world. The mundane becomes extraordinary in the minds of the uninformed.
So, at the risk of a few unpleasant words from the folks described in the above quotes, or hearing the same old "tinfoil hat!" insult, or the odd debunker trying to prove something he or she can't, though thinking their word is higher than anyone who talking about the possibility of anything UFO related, I am going to keep going at it, using the proverbial shovel to dig up any bits of information and knowledge that gets one closer to the truth.
If I were the USAF and I wanted to keep anything legitimate regarding planes currently being tested at Groom Lake or Dugway, I'd just sit back and let the UFO community spin fantastic tales of beings from outer space and watch as anything genuine gets buried under layer after layer of nonsense. It's the perfect disguise.
Given the amount of crashes that have supposedly happened, where's the bit of alien tech someone saved by getting it before the military got there to cart it off? There's a lot of camera phones out there... where's the amazing video that cannot be proved to be anything else but "alien tech"?
Also, the "mythology" is ludicrous as it is, featuring such wonderful technology as UFOs that can't function in rain. Any rational mind looking at it will see what is self-evident: that UFOs are a fantasy.
