I've never seen some of the footage in the link. I can't even begin to think the destruction one of these would have on a large city. The music sucks but you get the idea. Pretty intense video. I can't even imagine anything remotely close to one of these getting into the hands of the wrong people/country.
Sorry for the rant but the video struck me weird.
Check it out for yourself
