that definitely answers part of it, but how would they make it look like the camera hit the ground? they'd have to boom down, and have the boom arm touch the ground at the end of the shot, and make it stop abuptly. can that all be done with a motorized head, and if so, wouldn't the motorized head be underneath the camera, and thus make it impossible for the camera to appear as if it is on the floor? i dunno, i probably sound ignorant right now.
