Water is a very interesting substance, in that it is almost "non-compressible." When you dive into a pool, you are not compressing the water, just moving it out of the way. So the pain is directly related to the speed of impact, and frontal area. In other words, a belly flop off the low board might hurt, but it won't cause any damage. However, a belly flop off the high board is going to cause some serious damage. Lowering the frontal area by making the dive vertical will help .... but the downside is the increase of speed. Terminal velocity of skydivers (horizontal/arms outstretched) is about 120 mph .... vertical can get up to 180-200 mph. Serious damage starts to occur at speeds above 80 mph. A stat that I referenced below shows a 87% mortality rate in falls into water above 150 feet.

About the same height that you can dive into it without injury from a stationary platform. About 30 feet for an experienced diver.
While there have been a few cases of people falling into water or even solid ground without benefit of a parachute and surviving, those are clearly flukes.

Nick Alkemade was shot down over Germany in World War II, he fell 18,000 feet without a parachute and survived, his fall was broken by pine trees and snow, he only suffered a sprained ankle. Once he landed he sat down and smoked a cigarette

The US Coast Guard won't drop their swimmers from over about 30 feet. By 100', you'd reach enough speed to splatter like hitting concrete.

6 3/4 miles high on a warm day

Depends on the strength of the bungee cord.
