Kittenger wasn't trying to set a speed record. In fact, much of the mission was an f-up. They were testing human limits, and it was a secret; so, if he had died --which, btw, he almost did-- he would have been as well know as most test pilots. Personally, I think this guy will survive. It's just a matter of a functioning pressure suit ... that won't ignite or steam him like a lobster. Those, and providing air --in the correct ratios adjusted for altitude-- are just (difficult) technological issues. A space suit costs a couple million, but neither it, nor the astronaut, would survive a drop from space. I think the aeronautics agency gave up (afaik) on raising Kittenger's limit because they didn't see any point. NASA has worked on escape pods that work for aborted launches.
Imo, a multi-occupant escape pod is a better alternative to an individual jump, if only for psychological reasons. At any rate, nobody can say that this guy --if he jumps-- has more cujones than average. He is also way too smart to deserve a Darwin Award. That'd go to a guy who sets up his own balloon in the backyard and goes up as high as he can with an oxygen bottle stolen from the dentist's office, wearing a Northface jacket, using a surplus parachute.
... Don't laugh.
