120,000 feet - 23 mile freefall. This will be interesting.

It's been a long time in the planning. I hope all goes well.

In terms of velocity and pressures exerted will this effect the human body? Definitely very exciting though!

No, but it might affect it smile

Check out Joe Kittinger's record - the one that Baumgartner is attempting to break
Amazing.

Not doing anything that hasn't been done before - so the AFFECTS on the human body are already well understood.

Just ask Joe Kittinger.

Is that right? I thought, though could be wrong, that this jump will be the first person to break the sound barrier in freefall. So not exactly been done before.

It was thought that Kittinger broke the sound barrier too. Although, with the air density so low at that altitude, breaking the sound barrier is not that big a deal and is hardly noticeable.

BBC keep saying he will be the first mnan to break the sound barrier in free fall. Has Joe Kittinger's feat half a century ago been forgotten?

I can only find quoted values of a maximum 614 mph, which would have been slightly below the speed of sound at -94F,( lowest temp Kittinger experienced), of 639 mph. So close to supersonic yes, but not actually exceeding the speed of sound.

But isn't the speed of sound also dependent on atmospheric density? At 100,000 down to 60,000 or so, the density is not that great.

I think they were never 100% sure but I read for years that he had broken the sound barrier. I'm sure they stated this in the BBC (ironically) documentary series "Reaching for the Skies".

Its mainly dependant on the air temperature. Pressure and density cancel each other out.

I don't think anyone is forgetting Kittinger and he doesn't seem to think this jump is useless - he is on the team. I think he was on Radio 4 a few months ago talking about the attempt and confirmed that he did not go supersonic on his jumps.

There seems to be a great deal of mutual respect between Kittinger and Baumgartner.
