Default Skydiver gets ready for 23 mile jump

He wants to drop from 120,000 feet and check parachute at 5,000 feet. Is this guy nuts or what? Current record is from 102,000 feet by USAF Col. Joe Kettinger in 1960.

I wonder, how do parachutes resist the "impact" of drastically slowing a man at terminal velocity when he opens his canopy?

Here's the perfect explanation to that question, and it ties in perfectly with the current topic.

I wonder with the higher start and the lower deployment, how severe is that impact coing to be?

Surely he is going to use a multiple stage parachute like Kettinger did

He'll actually slow down as he descends into the thicker atmosphere.
By the time his chute deploys, he'll be going no faster than if he'd jumped from an airplane.

The multiple drogue chutes Kittinger used were not to slow the descent, a very common misperception, but to eliminate the chance of a blackout inducing spin. He almost died during a test jump in '59 from such a spin.

From everything I've read, Baumgartner thinks he can maintain control using hands, feet and legs like any other dive, and has no intention of utilizing a drogue chute to maintain control. We'll see.

Doesn't terminal velocity mainly revolve around the principle of a lack of further acceleration?

What if he sticks his arm out or doesn't? either from a plane at 20,000 or from a balloon at 120,000? what if he sticks both arms out in an las vegas elvis suit?

Exactly what I was thinking.

Also, does the person feel any shock from the opening of a shute at such a velocity? And how does that feel/how does one deal with that?

Yes but the chute harness distributes the shock over the body to lessen it's impact.

One tries not to get ones testicles trapped between the leg strap and thigh.

Can we move on from skydiving - I've done it (slightly lower than 23 miles), I can't afford to do it now but still want, want, want!
