By Kittinger's own calculations he did not go faster than sound. At 18,000 feet when he opened his parachute, he would be at his maximum velocity, which Kittinger calculated to be 614 miles per hour, at 18,000 feet, the speed of sound is 712 miles per hour. He reached Mach 0.86, about as fast as the average passenger jet.

Ever heard of really thin air at that height? And by the way, the speed of sound is lower at high altitude.

How can that be? Anyone ever heard of terminal velocity?

Who is "she"?

Apparently one of his gloves unpressurized and his hand was swollen.

He was the first person to go supersonic without an aircraft, not the first person to go supersonic.

Is the sky really black at that altitude?

oh, you were faster than me :) same idea

I had a Squadron Commander who once told us about her attempt to break the world record...but she couldn't get her leave approved, and it never happened. I wonder if it's true...

That´s not right! Chuck Yeager´s supersonic flight was in the year 1947! He reached a speed about MACH 1,0015.

And the first person to go supersonic... (This was before Chuck Yeager's supersonic flight in the Bell X1)
