I agreem the rumours about what have been seen around Area 51 proberbly have trusth in them. Over the past hundreds of years theres always been advanced technology owned by the militaries of the world so nowadays theres going to be no diffrent, how advanced they have gotten is open to discussion really though. The 1 that struck me though is the satelite pictures of what could have been a cloudbut looked more like a smoke stream that had came from a plane that circled half the world and wopuld have meant that the aircraft would have had to have travelled half the world in less that an hour or something, pretty cool lol
