I am not mocking the guys, but the fact that you jump from planes (spaceships? lol), even so incredibly high doesn't make you special. Still, this looks awesome, wonder how much the ride to altitude is :cool:
 
One of the problems at that altitude is that if you begin to spin there is nothing to slow you down(the guy who holds the record for jumping was told if he tripped while leaving the balloon he could break the sound barrier while spinning at similar speeds, turning him to mush), it is a technical as a lab procedure not to die while decending, you can't make wrong move.

Would be very cool but I will wait till you can do a full head dive through the outer atmosphere and have a bit of fun while up there :)

I think this is the thing I have dreamed of doing for a long time.

Always looked at footage of spacewalks and engineers/scientists in orbit and just imagined letting go, letting the earths gravity pull you back in. At that distance I bet the sensation is amazing. When they pull this off, it will be a great accomplishment.

2500 mph? Maybe not quite so fast . :p

More drag means slower terminal velocity. Increased mass means higher terminal velocity. An object moving downwards at greater than terminal velocity (for example because it was affected by a force downward or it fell from a thinner part of the atmosphere or it changed shape) will slow until it reaches terminal velocity.

Wont it get a bit hot churning through the atmosphere at those speeds?

That's what I was wondering. When you hit the atmosphere, you'd burn up! You can't even slow yourself down first because your parachute wouldn't work until you reach the atmostphere! Bit of a catch 22 really.

Terminal velocity does change with mass, it changes with air friction (2 objects same weight but different shapes), the force due to gravity acceleration is bigger on heavier objects tho, so will reach terminal velocity quicker.

Also how can something slow until it reaches its max speed? It will accelerate until it reaches its terminal velocity granted the rate of acceleration will decrease the closer it gets to its terminal veloc.

the only effect of air density is on the friction, less friction = higher terminal veloc, closer to sea level = higher air density, high alt = less.

You're not arguing with me you're arguing with his link. I was merely saying that his link told him the answer to his question.
