I wish him a successful jump.

I wish him a successful landing!

here, here! good on him - he's doing carpe diem..

He is so lucky to be able to fulfill his dream.

Weightlessness at 130,000 ft. in a balloon? Impossible. He will experience weightlessness only for a few seconds when he steps out and begins his fall. Astronauts experience weightlessness only because of their ultra high velocity, and the centrifugal force of their orbit cancels the gravitational effects at their distance from the center of the mass of the earth. A balloon with an insignificant velocity, still relatively close to the earth's mass will experience .95 G, or basically the full gravity we experience.

Weightlessness or not he has a lot of bottle it's a long way down, hope he makes it OK !!

He will have a lot of trouble with extreme heat. Then a lot of trouble with extreme cold. I hope his source of oxygen can stand extreme temperatures, pressure changes, and shock. He will be at terminal velocity, and I hope his braking system can also withstand all those forces. Personally, just give me a beer and a fishing pole at Inks Lake.
