the glorious guberments regularly release declassified documentations, usually after 50 years of it being classified, this is common knowledge as far as im concerned, and it is also a well know fact that any new technology that is found is jumped on by the military industrial complex, we very rarely get anything before the military gets their hands on it, e-cigs being a recent example as far as im aware. i remember when i was younger DVDs had just come out or so i thought, my old man found it hillarious told me they tried introducing these DVDs 15 year previous but the mass's were apparently happy with betamax and rejected DVDs untill my generation came along, what im telling you is very real the history you were taught was not a true account of history by any short of the imagination :/
