They put a lot of hard work into that one. And yes, many of the spectacluar jumps end on padded areas and are otherwise cleverly edited multiple shots, so don't try this at home. Even so, one of the stuntmen involved dislocated his foot when jumping down a ladder (?http://youtu.be/MhXAVmGob_A#t=369s) and had to be treated at a hospital.
