Thursday Baumgartner – with his helium ballon, pressurized capsule, full pressure suit and from 71,581 feet – jumped and parachuted safely to the ground.
He reached speeds of 364.4mph in this jump and when he attempts the full jump from 23 miles later this summer, he is expected to be the first person to break the sound barrier outside of some sort of capsule. All of this is an attempt to break the record of Co. Joe Kittinger who jumped from 102,800 feet in 1960 and never quite got to the speed of sound, although there are many false reports that he did.
Thursday’s jump lasted 3:43 before he pulled the ripcords for his parachute and the successful test makes him only the third person in human history to have jumped from that altitude.
You can find out all sorts of info from the official Red Bull Stratos site.
