oh my god. oh my god. look at that. harold brooks: one of the things about a tornado is that it's producing a lot of small pieces of debris that are flying at, you know, 150 miles an hour. and even ordinary objects, dinner plates, two by fours, become really, really deadly at those kinds of high speeds. jim riek: i knew after joplin how destructive a tornado could be. it was moving so slowly that it was like a blender. everything on the ground was getting totally mixed together. and it just hits you again and again and again and again. i saw a piece of cardboard that actually penetrated into the exterior insulation finish system on a school. at the hospital, they had $1 million helicopter. all of the rotors are gone.
