Are you checking out the live stream of the Stratospheric free fall attempt?
So this guy is ascending in a helium balloon capsule to the stratosphere (~120,000 feet). In a spacesuit, he plans to jump out of the capsule and free fall, hoping to be the first human to break the sound barrier outside of an airplane.
I think he's nuts, but I'm watching with a wee bit of morbid curiosity. No one knows for sure the effects of the fall or breaking the sound barrier on the human body.
