A bit of relative data is available from one of the books in the Resource Section.
The author, a doctor, explains why the biggest cauee of failure is insufficient height. His conclusion at the end of the section is falls from 150 feet on land and 250 on water are responsible for 95 to 98% of fatalities (not respectively, but equally for both).
Most jumps however, are shown to be from 20 to 50 feet, which probably account for most failures.
Make sure you don't flip too much in air, wear clothing which may get stuck in the way of trajectory, or act as a cushion/safety net/parachute, for example dresses for women, or baggy clothes.
Here are results from a pig being dropped onto both pavement and water from 600ft. (182m) In both cases, the pig lands on its side. Definitely fatal in either case.
I know you posted for an illustration, but they dropped off at the same height. It wasn't a fatality in the second case? 16 fractures sounds like a painful time agonising, alone and without help, in terrible pain. There was no decap on the second attempt.
Thanks for putting out, I always thought a landing on one's spine/ back of neck was best (nobody ever talks about it, I must be stupid and wrong), but interestingly, landing on the side works.
And btw, in case ye didn't know it, Grant died. Good-natured guy, very bad.
