@Joozey:
Well I wouldn't use this document as the ultimate proof of aliens, flying saucers & stuff. It's a proof though that the story which insistently gets denied as nonsense and stuff crazy people came up with in the 80s (because that's the time the Roswell incident got real public interest) doesn't seem to be as far fetched as it's being told if even years after that incident (I think Roswell was 1947 - that report is from 1950) an Air Force official states those facts...

I think it's a good start though to ask some serious questions based on something reliable...
