Could a man in normal health survive a fall from 30 stories up if he fell into a van that was in motion and full of 10 used mattresses? and if he did, is it possible that he went thru the roof of the van, thru the mattresses stored inside and then thru the bottom of the van landing into the pavement... and survived.

In my scenario, he breaks every bone in his body and suffers severe internal injuries, is in and out of consciousness for several days, slips into a coma for two weeks and then expires... is any of that realistic?
