UFO's and extra-terrestrial life

[Lixma]

People should hear what is being said rather than just listening to who is saying it.

In that video Cooper describes seeing extra terrestrial craft while flying in Europe during the war. Assuming these things are physical real (which, given the description of them making impossible manoeuvres it seems unlikely) then how on Earth does he know they are extra terrestrial in origin? Answer: he doesn't. He hasn't a clue what he saw....but a lot of people really want it to have been extra terrestrials; including, it seems, Cooper.

Note also his account of the saucer photograph. A couple of guys under his supervision claim to have taken a picture of a flying saucer that helpfully landed in front of them and then flew off again. Cooper then, after establishing the proper procedure for these things, instructs the cameramen to send the negatives off to God knows where. End of story. Call Spielberg!
