Has it ever occured to you that... Some things such as the incident in 1965 where we (the US) hauled away objects for national security, might be something else? Like perhaps a material much denser the uranium... capible of making a warhead a thousand times greater then a modern nuclear weapon. Other countries might not want to hear we have weapons capible of blowing up an area the size of the state of texas now would they. I shouldn't have even put that out there. It doesn't matter though since i'm just some wacko on a internet forum as far as anyone is concerned... I just don't see why everyone assumes these are alien crafts. A meteor containing materials foreign to the earth can be just as valuable and dangerous to national security.
