I've been following Felix Baumgartner and Red Bull Stratos for a while yet. I am a big time fan and supporter!
Today will be his day. I hope all will go well during ascent and the jump.
What he is doing here is truly incredible... simply beyond words...
Austrian Felix Baumgartner set for skydive record attempt
The Austrian skydiver Felix Baumgartner will attempt to become the first human to break the sound barrier unaided by a vehicle.
He is going to jump out of a balloon at more than 120,000ft (36.5km) above Roswell, New Mexico.
In the near vacuum at that altitude, he should accelerate beyond about 690mph (1,110km/h) within 40 seconds.
Assuming all goes well, he will open a parachute near the ground to land softly in the local desert.

This balloon is now useless. The commentator says it cannot be reused. There is another spare balloon on site.
Also they had a problem with one of the on board radios in the capsule that was not working properly.
I took a screenshot
Felix Baumgartner in his capsule when they announced launch abort.
Launch called off due to wind gusts.
Well, that is anticlimactic. Once they started inflating the balloon it began to be whipped in the wind and it became apparent that full inflation would be impossible.
"Whoa, gusty winds are taking that balloon down now," said the Red Bull announcer. "That's going to be a problem. There's the decision. Abort the attempt.
"May or may not be tomorrow" -commentator.
"That's the decision. This is going to be off for today. ... They had the window for a short while. But the winds are a huge concern."

There was a better way to fly it was called Concorde

Quoting klemmi85 (Reply 4): Does he jump from that height because the atmosphere provides very little drag so he can actually accelerate enough?
Yeah. I'm a bit hazy on the physics but he will be so high that there will be no atmosphere to create drag. He will keep accelerating for the first min or two, this is the point when he should exceed the speed of sound. After that the atmosphere will slow him down until he opens the chute at 5K feet.

Quoting EagleBoy (Reply 12): Yeah. I'm a bit hazy on the physics but he will be so high that there will be no atmosphere to create drag.
A side effect is also that it is easier to break the sound barrier at that altitude. The speed of sound is function of temperature and drops as the temperature drops. For example, at sea level in standard conditions - 15 degrees Centigrade - the speed of sound is about 661 knots/761 mph; at 120,000 ft - where the temp is about -40 Centigrade - it drops to 611 knots/703 mph.
EDIT: at 36,000 ft - where the tropopause starts on average - the temperature is even lower, -56 Centigrade in standard conditions, giving a speed of sound of "just" 589 knots, or 678 mph .

Watching the live action on ServusTV, he just passed 62,000ft at -60°C, breathing 100% oxygen. The so-called "Armstrong Line" is going to be crossed soon, an altitude at which man's bodily fluids would start to boil without adequate safety measures.
Live feed clearly shows the curvature of the earth, cam setup is very high quality, I hope the jump will be just as impressively filmed as the launch.
All the best to Felix! This is a big achievement to all of humankind!
// You know you're an aviation enthusiast when you look at your neighbour's cars and think about fleet commonality.
I captured screenshots during ascent and jump/freefall/landing.
I will post them on this thread later.
What a day!
World's Highest Skydive! Daredevil Makes Record-Breaking Supersonic Jump
Unofficial results of the jump showed Baumgartner spent about 4 minutes and 22 seconds in freefall, a bit short of the longest freefall record, but that he had a speed of about 700 mph, which would clinch the supersonic milestone, Red Bull Stratos officials said.
