Supersonic Skydiver
Skydiver preparing for 120,000-foot supersonic fall - CNN.com
Anyone want to speculate on the physical effects of breaking the sound barrier on a human? I'm not entirely sure I understand what happens - the sound waves of your passing are in essence building up behind your axis of flight right? So isn't it dangerous to come back from supersonic? Depending on the altitude at which crossing that threshold occurs, there would be more or less pressure built up behind you, so I could see that wreaking havoc with his parachute or maybe tossing him around a bit extra? Kudos to Red Bull too

Opulence - They Swiped It
 |
This gives HALO Jumping a whole new meaning (High Altitude Low Opening)
I watched a documentary on the US Army Precision Paratroop unit. They basically do Demos at Airshows and such. Well one trick they do is 2 guys basically shoot past each other at like 350 MPH. One time the 2 guys actually hit each other. It severed one guys legs completely ! |

This dude did not need red bull.
He weighed 150 pounds. 140 pounds of that were brass balls the size of your head.  19.5 mile freefall.

I want to see the math on him hitting Mach 1 in free fall. Jumping 120,000 feet is nuts and all but I'm not sure the breaking the sound barrier claims might be hyperbole.

True, his terminal velocity might be much less than the speed of sound.

Hmm...
According to wikipedia, the speed of sound is 1,125 ft/s. According to Terminal Velocity if the guy is 200lbs and about 2sqft in area, his terminal velocity is 2995 ft/s. I wonder how much force a parachute can handle... |

1893 ft/s = 1290 mph. That's almost Mach 2 if he hits it.

Now, this other calculator gives a different result:
