Austrian Felix Baumgartner said he did not notice the moment he broke the speed of sound during his record-breaking skydive of 39 kilometers (24 miles) from a helium balloon to Earth.
Baumgartner, 43, achieved the speed of 833.9 mph or Mach 1.24 during his dramatic free fall on Sunday, but said he did not feel anything during the jump.
"When I was standing there on top of the world, you become so humble, you do not think about of breaking records anymore, you do not think about gaining scientific date. The only thing you want is to come back alive,” he said at a news conference after the jump.
The entire descent - from the stratosphere to New Mexico - took four minutes and 19 seconds. His parachute opened to help him through the last phase of the journey.
“I had a lot of pressure in my head. But I didn't feel like was passing out,” the skydiver said.
With this successful jump, dubbed "Mission to the Edge of Space" on his Web site, the Austrian daredevil outdid retired US Air Force Col Joe Kittinger, breaking his 1960 record.
“Records were meant to be broken. Better champions cannot be found than Felix Baumgartner,” Kittinger said at the news conference.
