SpikeStrip: it's not a free fall and he's not "fearless."


How's that? I don't follow.

NoWhiskeyWeGoNow: Gough: iron_city_ap: I thought it was impossible for humans to exceed 9.8m/sec without some form of thrust. Your wife falls as fast from a 50 story building as she do from a 100 story one. It just takes longer.

You forgot another second. It's 9.8 m/sec^2 and that's the rate of acceleration . After one second, you're falling at 9.8 m/sec, after two seconds, it's 19.6 m/sec, and so on. The big difference at high altitude is that the air resistance is much lower, so terminal velocity is much higher.

I love it when I get to post this.


My god, I love that picture. Even adding in my feeble attempt at understanding what that feeling was like, the man was on the edge of space, beyond any possible chance of saying "actually, I'd rather not"...and just took that step. That one step. At once being separated from your last bastion of modern technology (the gondola of the balloon) and going for broke. I'm sure he had confidence in the science behind all the apparati he was wearing, but as far as a true "leap of faith" this is nigh unsurpassed.

I feel I need to post this Boards of Canada video, as it was my first introduction to Kittenger and his leap:

COLUMBIA CREW SURVIVAL INVESTIGATION REPORT 3-89
3.4.3 Identified events with lethal potential
3. The third event with lethal potential was separation from the crew module and the seats
with associated forces, material interactions, and thermal consequences. This event is the least understood due to limitations in current knowledge of mechanisms at this Mach number and altitude.

Go up high enough up and there are less air molecules than there are at sea level to plow through so you can go faster.
