Actually Doc, almost the entire passenger side of the cage was ripped from the car - Allen's seat and harness was still intact - and the chassis rails were really twisted up. I think there was some serious concern about chassis build quality for the Pro class.
When I watched it, I was thinking" Holy fuck!" It was one of those things you hope to never see happen, but still want to see every replay from every possible angle.
