Here's a guy dropping 150 feet onto what looks like about 15 ft of cardboard boxes.
I'm estimating an impact speed of something like 60 mph and an average acceleration
of about 8 or 9 g as opposed to the ~110 mph and ~40 g to be expected for someone
falling from 1500 feet onto 10 feet of cushion.

I'm willing to admit that I wouldn't want to have any part of an event like that unless the stuntman
had some way of braking his fall substantially below the otherwise expected 100+ mph terminal velocity.

surprised at the derision heaped on Mythbusters. In this episode, do
they ever claim to demonstrate that 4 inches of bubble wrap will
protect a falling person? Do they actually demonstrate the opposite?
the stunt equivalent of bubble wrap - stacked cardboard boxes. They were
stacked about ten feet high, its true, but I imagine this list would
poo-hoo this stunt on theoretical grounds if they had not witnessed the
circumstances.
Come on, let's hear it for the impulse-momentum equation... :-)
