Live news feed of skydiving record

Recommended Posts

I'm watching the live news feed (no I dont' have a life) and Fournier was in his yellow suit and helmet and he walked from the capsule to the transport vehicle and they drove away.

A few minutes later the crane holding the capsule drove away from the lauch site too. The balloon still left uninflated was left on the ground.

This is his 3rd attempt and he must have a complete set of wankers working for him. Balloon shreads one time, a valve fails another and will not inflate and he simply can not seem to launch a balloon. Makes you wonder if that can not be accomplished, what issues can there be with his suit ?

Screen shots attached.

It is Monday morning on the 26th. Here is a live news feed from CNN of the record attempt. There is no sound because it is just a news camera set up pointing at the launch site.

Clicky

This may be a fundamental lack of knowledge about physics, but why is it that this and joe kittinger's extremely high exits make for such fast freefall speeds? In other words, when we skydive we hit terminal at around 120 (on the belly), and stay that way until deployment. Why will Fournier break the sound barrier? Why do they accelerate past our terminal velocity?

Terminal velocity is a function of gravity pulling us down with the resistance of the air. Hence, my neutral body position's terminal velocity in my baggy RW suit is in the neighborhood of 130mph. In jeans and a t-shirt its closer to 140mph.

The higher you go, the less air, less resistance (drag) slowing you down.

All objects fall at the exact same rate regardless of size, weight and shape in a vacuum.

That's the lay person's version of some complicated math. :P

Higher altitude = lower pressure = less friction = higher freefall speeds. During the WT06 record attempts, we were going to 26,000 feet and were hitting 155mph absolute speed in freefall on our bellies. (Slowed down to 120mph by breakoff.) Didn't seem any faster, of course, since you airspeed is always the same.

Slightly expanded layperson explanation:

Terminal velocity is function that also includes air pressure.

Your terminal velocity is faster when you fall at 30,000 feet than at 10,000 feet because of lower air pressure.

Now, when you fall from space altitudes where the sky is black, it's now almost a vaccuum so terminal velocity can actually be above supersonic speeds.
