Talk about "HALO"! I may just have to tune in if I can. Reminds me of the Starship Troopers (the book, not the movie).

I wonder what the shock-front will do to his suit and him. If he's successful at reaching mach 1. I seem to recall that it wreaked havoc with early airframes. But aeronautical engineering isn't my area.

just watched something about that on the TV ...

iirc, 'problem' was that AT Mach 1, controls didn't work: the shockwave messed with the flow over control surfaces.

if so, not a problem for this guy

Yes, I remember that. But I believe it also had a tendency to rip off wings due to the erratic airflow over them. What would that do to this guy's neck, for example? Maybe nothing. I really don't know. You would hope someone involved has already done the calculations for him.

One of the Stratos/Red Bull team members is an acquaintance of mine through flying (he's looking after the GPS data recorders and record keeping to establish the jump records). He recommends the Wired article:

Here's a much less professional presentation he made to a bunch of us soaring pilots here in MN:

*i* would hope that someone has run a crash-dummy through a supersonic wind tunnel

FWIW: they started preps last night for the jump this morning, but had to put it on hold due to winds aloft.

They need winds on the ground to be 4MPH or less to be able to launch the balloon safely, and they need winds aloft to be such that they won't carry the capsule into Mexico or beyond their ability to retrieve it.

Naturally, New Mexico is known for its windiness. (Popular wisdom has it that's because Arizona bl*ws and Texas s*cks.)

Finally looking like stuff is happening on that live feed. Felix is in the capsule and they've moveed away the support fro the capsule - it's just dangling there from the end of the crane.

So now we've got a bunch of guys standing around staring up at the capsule. Wonder how many hours of boredom went into the incipient 5 minutes of terror? Hope this all goes well.

I think our firewall is blocking it. I'm just getting a "standby" message.

The setup for a 7AM/sunrise launch starts at 11PM the night before.

Launches are generally scheduled for dawn as winds tend to be the least active then. Winds on the ground need to be about 4MPH or less for a launch, and winds below 600' also relatively quiet (the balloon stands about 550' tall). If you look at photos of the Roswell launch site, you can see several tethered balloons around to indicate the winds aloft up to about 700'.

I'm sorry to see that they're standing down, and will try again on Thursday if the forecasts are good.
