its happened before... just ask the dinosaurs...

Nick, just found it interesting, as well as what you said... they have upped everything now, 55 feet, 14000 tons, 46,000 MPH, and 500 Kilotons of energy... and you are right, we have no missiles or anyone on the planet that could catch something like that...

fyi, the 2 bombs we dropped on Japan, were both under 25 KT's.....

what do you think it is that looks like its flying and slamming into the back of it? vapor trail forming from going so fast? or peices breaking off?
