ripped from slashdot:

"The Observer has a story about a retired French army colonel who is soon to make a free fall parachute jump from 25 miles up. In the process he will break the sound barrier, reaching a top speed of mach 1.68 before he opens his parachute 1,000 metres above the Earth. Of course, if the chute doesn't open, the hole he'll make will be about 1,000 metres deep." Well, actually his max speed will be high up and near the earth the atmosphere will have slowed him down to terminal velocity."

heh...mach 1.68..thats CRAZY.
 
What kind of parachute could possible stand up to that kind of force upon opening?? 😕

Muchless without the body snapping in half! :Q
 
a us test pilot did something similar in the 60's (im not sure how high though, i believe it was abot 25000 feet - nowhere near this high). he needed oxygen mask, and he broke the sound barrier. it was on the history channel, on a show about the history of parachutes.

It will be no different force wise than parachuting from any distance above which he would reach terminal velocity in the atmosphere.

He will be doing somewhere between 120 and 210 mph when the parachute opens. More than slow enough for a regular 'chute.
 
That's 132,000 ft up (woot!). I think that when you break the sound barrier, you don't actually hear the boom because you are ahead of it. The boom follows behind you.
 
He'll be wearing a pressure suit with O2, what they don't know is what happens when he hits the sound barrier; hopefully nothing since the atmosphere is so thin, and if heat will be a problem as he's descending & the atmosphere gets thicker.
 
I saw on the History channel this guy who jumped 100,000 feet from a ballon. There was not enough air molecules to ripple his suit. =0
