Several years ago we had a Super Comp dragster come over to Firebird from New Mexico for a weekend event. He cleared the lights at 175 mph with the throttle stuck wide open (HEY, the return spring worked when I teched it!!!!!!) and continued to accelerate past the 2,000 ft. shutdown area and on into the desert at the end of the pavement. I don't know when the engine blew, but it apparently worked itself to death at some unknown rpm (no rev limiter), so it's anyones guess what the speed was before the car finally made a left turn in the dirt and began flipping, rolling, flying, etc, etc. I jumped into one of the rescue trucks and hauled butt to where I thought he would be. It took us quite a while to find him upside down under some brush and several mesquite trees. There was sheetmetal and parts everywhere (we saw sheetmetal up in the tops of the surrounding trees) and a scoop in the dirt which we saw on the way to find him about the width of the cage and some six to eight feet long and about a foot deep where the top of the cage had gouged the earth out like a giant ice cream scoop. It must have done that going backward through there, because when we found him, there was no dirt packed in the cockpit. There was only the bare chassis sitting there with him still belted in it, upside down with no tubing whatsoever forward of the footbox or rearward of the motor plate. We righted what was left of the car and got him out. Miraculously, nothing was broken and he had no injuries whatsoever. Of course, it rang his bell and he was a little incoherent for about an hour or so, but later he was down there gathering up what was left of the car. My point is that the cage was intact, a tribute to the design and construction of the car.
