Imagine flying in a plane to 96,000 feet, three times higher than a commercial flight -- and then jumping.
That's exactly the feat accomplished today by Austrian daredevil Felix Baumgartner, who tumbled nearly 18 miles before safely landing in Roswell, N.M.
Amazingly, Baumgartner jumped from 36,000 feet above "Armstrong's Line," the point where water boils at "human body temperature."
Baumgartner was wearing a pressurized suit NASA hopes may one day aid astronauts trying to return to Earth in an emergency situation.
This isn't Baumgartner's last jump: In August, he'll try to beat Joseph Kittinger's decades-old record with a leap from 120,000 feet.
