RE: terminal velocity
Nope...
Skydivers have a very bad glide ratio, (about 1:1 max with a standard jump suit) and you definitely don't want to land on any surface, without a parachute. You could do it, but only once! I've daydreamed about jumping out of a crippled plane and heading for a lake, and I suppose anything is worth a try, if the option is certain death, but...
You're right about terminal velocity... Around 120 mph, depending on the skydiver's weight, size, body position, jumpsuit type, etc.. The "envelope" is approximately 90 or 100 mph at the absolute slowest, to nearly 300 mph for the "skydance" types in tight-fitting jumpsuits, in a head down dive.
Skydivers stick pretty close to the "32 ft. per second, per second" acceleration rate, and so the typical skydiver jumping out of a slow Cessna will take 3 or more seconds to get to terminal velocity. Cliff divers and other high divers going into water don't come close to terminal velocity, and also are at about the edge of survivability. You hit the water going 100 mph, it's not going to be pretty. But the thing is, you'd be going faster. "Terminal velocity" is typically measured by skydivers falling "face to earth", which is not how you'd want to land in water. When you straighted out into a head first or feet first position, you'd accelerate to as high as about 180 mph, even in a pretty big jump suit. In a clunky sort of way, it's like other airfoils we discuss. A pretty big skydiver in a pretty big and flappy jump suit is flying with a lot of drag, increased by the turbulent airflow around the flappy jump suit. The "skydance" types, typically skinny folks in skin-tight jump suits and full-enclosure helmets, are a lot more streamlined, and can fly faster. Just like an airplane, more airspeed gives more control.
If you ever have done a formation skydive, and have seen another skydiver whiz by in freefall, as you open your parachute, you know that landing in water will probably not affect the outcome. (150 feet per second to quite a bit faster! )
An interesting theory has been proposed more than once...
As tightly-grouped formations of skydivers grow in size, they actually decelerate, due to the drag. It's been conceptualized that if 100 or so skydivers formed a delta-shaped formation, and if all 100 of them were able to think and act in unison, to dive down, gain some speed, and then make the formation "flare", they might be able to actually land such a formation, if they all wore roller skates, (on their knees and hands, since you couldn't "stand up" ) and let the nose drop gently. If I remember right, I think the landing speed would've been around 90 mph forward, with something like a 20 ft. per second descent rate. (which is rough!) The catch is that if pretty much any of the 100 skydivers screwed up, (especially if it was low) the entire formation could collapse, or simply not maneuver correctly enough to survive. I hope very much that no one ever really tries this. (!)
