The Bruce Allen clip is particularly scary because if you pull a few screen shots from the video as the car is rotating in the air, it looks to me that a lot of the passenger side floor & center floor bars are now gone. The passenger side floor looks to be missing the rocker bar, outer floor diagonal, inner main frame rail, passenger side of the double frame rail, and possibly the main rails center "X" brace.
It kinda looks like the only thing remaining of the car's driver/passenger compartment floor that kept his seat (and butt) in the car was the driver side inner main rail & drivers side double frame rail bar.
It would have been interesting to see better pics of the chassis damage aftermath to see what is still there.
