CAPE CANAVERAL, Fla. – His blood could boil. His lungs could overinflate. The vessels in his brain could burst. His eyes could hemorrhage.
And, yes, he could break his neck while jumping from a mind-boggling altitude of 23 miles.
But the risk of a gruesome death has never stopped Fearless Felix Baumgartner in all his years of skydiving and skyscraper leaping, and its not about to now.
Next Monday over New Mexico, he will attempt the highest, fastest free fall in history and try to become the first skydiver to break the sound barrier.
So many unknowns, Baumgartner says, but we have solutions to survive.
The 43-year-old former military parachutist from Austria is hoping to reach 690 mph, or Mach 1, after leaping from his balloon-hoisted capsule over the desert near Roswell.
He will have only a pressurized suit and helmet for protection as he tries to go supersonic 65 years after Chuck Yeager, flying an experimental rocket plane, became the first human to go faster than the speed of sound.
Doctors, engineers and others on Baumgartners Red Bull-sponsored team have spent as much as five years studying the risks and believe they have done everything possible to bring him back alive. He has tested out his suit and capsule in two dress rehearsals, jumping from 15 miles in March and 18 miles in July.
Baumgartner will be more than three times higher than the cruising altitude of jetliners when he hops, bunny-style, out of the capsule and into a near-vacuum where there is barely any oxygen.
If all goes well, he will reach the speed of sound in 30 seconds at an altitude of about 100,000 feet. Then he will start to slow as the atmosphere gets denser, and after five minutes of free fall, he will pull his main parachute. The entire descent is expected to last 15 to 20 minutes.
He will be rigged with cameras that will provide a live broadcast of the jump on the Internet.
