Eric I posted this at the other forum but since you said you are going to hang around here for a while, I thought this might be of interest to you.
This record setting jump from 23 miles up is being carried live on Discovery Channel. He is still ascending. His current altitude is 57,000 feet. In order to reach the 23 mile plateau he must ascend to 121 thousand plus feet. I cannot even imagine what will happen to his body when he breaks the sound barrier.
