I feared the worst when he was going ass over tit. Anyone else feel their nuts go tight when he leaned over before letting go?

Thought you only had one ball?
The other one fell out of a plane door while I was being sucked off. It came down at 125mph and landed first, then this flipping tank came down after it and landed right on top of it. Unbelievable Jeff

Ok so the guy reached a fantastic speed at high altitude. He did so because the air is very thin so there is less resistance on him.Thats why planes fly at high altitude . . . .to save fuel.
As soon as he got to about 10,000 ft he would have slowed to 125mph which is the fastest he can fall thru the air. its called terminal velocity.
If you are a 50 ton tank or a 1 ounce conker you will fall at 125mph.
The guy is still bonkers tho and id like to get drunk with him

Some seriously misunderstood science here!

Objects in a vacuum will accelerate at the same rate. In the atmosphere we have to contend with drag. Drag rises at the square of speed. The amount of drag depends on the shape of the object. This is called the coefficient of drag or Cd. The 125mph figure you quote is the terminal velocity of a skydiver in the normal position of chest down with arms stabilising. In the head down position it can be almost double.

This is in the lower atmosphere where air density is higher. In the upper atmosphere with a much less dense fluid causing drag the terminal velocity is much higher as Felix showed today.

Anyway now that we've slightly bettered the 1960 skydiving record do you think we'll try to put a man on the moon next?

When you hit terminal velocity for the 1st time - generally more accepted as being around about 120mph - you hear a weird "rushing wind" sound in your ears.

Next time you hit it ... you don't.

True story!

What is terminal velocity through terra firma?

I have absolutely no bloody idea :( Is it relevant?

The point is that there is no single "terminal velocity" when falling through the atmosphere. It is different for different shaped objects and it changes as your density altitude changes so you cant hit it twice. You will reach the terminal velocity which will then change as you descend until you hit the ground. The ground being much denser than the air will cause a deceleration to the new terminal velocity of 0. The time taken to decelerate will depend how streamlined the object is!
