Daredevil set for death-defying skydive

2012-10-09 19:21

Roswell - An Austrian daredevil made last-minute preparations on Tuesday for a death-defying skydive from a balloon 37km over the New Mexico desert after delays due to winds earlier in the day.

Felix Baumgartner, a 43-year-old helicopter pilot, hot-air balloonist and professional skydiver, would break a longstanding altitude record and the sound barrier if the jump goes forward.

Baumgartner's team said the launch of a massive but fragile helium balloon that would carry him up to 120 000 feet (37km) above Roswell, New Mexico, had been scheduled for about 17:15 GMT.

The launch was delayed by about four hours because of winds above the launch site, the team said in a statement.

After they died down, Baumgartner, wearing a pressurised spacesuit, prepared to climb into a specially-made capsule that would carry him into the stratosphere.

"[The] countdown is officially back on," Sarah Anderson, a member of Baumgartner's launch team, told Reuters by e-mail.

If the launch proceeds, it would take about 2.5 to 3 hours to reach 120 000 feet.

The 850 000m³ plastic balloon, which is about one-tenth the thickness of a Ziploc bag, cannot handle winds greater than 9.7km/h.

Baumgartner hopes to break the record of 102 800 feet (31.333m) for the highest-altitude freefall, a milestone set in 1960 by US Air Force Colonel Joe Kittinger.

As he falls from 120 000 feet (36.576m) Baumgartner would also break the sound barrier. With virtually no air to resist his fall, he was expected to reach the speed of sound, which is 1 110km/h at that altitude, after about 35 seconds of freefall.

He would stay supersonic for nearly a minute and should freefall for a total of 5 minutes and 35 seconds.

When Baumgartner jumps from the capsule, the position of his body will be crucial, since there is no air for him to move around in. If he falls in a way that puts him into a rapid spin, Baumgartner could pass out and risk damaging his eyes, brain and cardiovascular system.

Baumgartner's safety gear includes his custom spacesuit that will protect him from low pressure and the extreme cold. Temperatures are expected to be as low as about -57ºC.

The near-vacuum puts him at risk of ebullism, a potentially lethal condition in which fluids in the body turn to gas and the blood literally boils. Severe lung damage could occur within minutes.

Helicopters equipped with newly developed instruments to treat lung damage will be standing by during Baumgartner's skydive.

"What we're doing here is not just a record attempt. It's a flight test programme," project adviser Jonathan Clark, a medical doctor and former Nasa flight surgeon, told reporters during a news conference on Monday.

Among those interested in the spacesuit research are commercial companies developing spaceships for passenger travel. The research could help people survive a high-altitude accident.
