World Record Holding Sky Diver Talks Free Fall

Posted: 07/05/2012 7:00 am

If all goes well this summer, Felix Baumgartner will break the world record for a parachute jump, leaping from 120,000 feet above the earth. Though Baumgartner's weather window began this week, those familiar with the Red Bull-sponsored project say the jump likely will occur in August.

If the Austrian daredevil is successful at the higher altitude, he will break a 52-year-old record held by an Air Force Captain named Joseph Kittinger.

On Aug. 16, 1960, as research for a then-fledgling U.S. space program, Kittinger rode his Excelsior III helium balloon to the edge of space, 102,800 feet up. Then, wearing a thin pressure suit and breathing supplemental oxygen, he leaned over the cramped confines of his gondola and jumped into the near-vacuum of space.

Within seconds, his body accelerated to over 600 miles per hour, approaching the sound barrier. After free falling for more than four and a half minutes, slowed finally by friction from the heavier air below, his parachute opened at 14,000 feet and he coasted gently down to New Mexico's desert floor.

Kittinger's feat showed that astronauts could survive the harshness of space with just a pressure suit, and that man could eject from aircraft at extreme altitudes and survive.

I had the pleasure of interviewing the legend, now 83, at his home in Altamonte Springs, FL, for my new e-book, The Right Stuff: Interviews With Icons of the 1960s. Here is some of what he had to say.

Jim Clash: Take us back to New Mexico and August 16, 1960.
Joe Kittinger: We got up at 2 a.m. to start filling the helium balloon. At sea level, it was 35 to 40 feet wide and 200 feet high; at altitude, due to the low air pressure, it expanded to 25 stories in width, and still was 20 stories high! At 4 a.m., I began breathing pure oxygen for two hours. That's how long it takes to remove all the nitrogen from your blood so you don't get the bends going so high so fast. Then it was a lengthy dress procedure layering warm clothing under my pressure suit. They kept me in air conditioning until it was time to launch because we were in the desert and I wasn't supposed to sweat. If I did, my clothes would freeze on the way up.

JC: How was your ascent?
JK: It took an hour and a half to get to altitude. It was cold. At 40,000 feet, the glove on my right hand hadn't inflated. I knew that if I radioed my doctor, he would abort the flight. If that happened, I knew I might never get another chance because there were lots of people who didn't want this test to happen. I took a calculated risk that I might lose use of my right hand. It quickly swelled up, and I did lose use for the duration of the flight. But the rest of the pressure suit worked. When I reached 102,800 feet, maximum altitude, I wasn't quite over the target. So I drifted for 11 minutes. The winds were out of the east.

JC: What does it look like from so high up?
JK: You can see about 400 miles in every direction. The most fascinating thing is that it's just black overhead. The transition from normal blue to black is very stark. You can't see stars because there's a lot of glare from the sun, so your pupils are too small. I was struck with the beauty of it. But I was also struck by how hostile it is: more than 100 degrees below zero, no air. If my protection suit failed, I would be dead in a few seconds. Blood actually boils above 62,000 feet. I went through my 46-step checklist, disconnected from the balloon's power supply and lost all communication with the ground. I was totally under power from the kit on my back. When everything was done, I stood up, turned around to the door, took one final look out and said a silent prayer: "Lord, take care of me now." Then I just jumped over the side.

JC: What were you thinking as you took that step?
JK: It's the beginning of a test. I had gone through simulations many times -- more than 100. I rolled over and looked up, and there was the balloon just roaring into space. I realized that the balloon wasn't roaring into space; I was going down at a fantastic rate! At about 90,000 feet, I reached more than 600 miles per hour. The altimeter on my wrist was unwinding very rapidly, but there was no sense of speed. Where you determine speed is visual -- if you see something go flashing by. But nothing flashes by 20 miles up. There are no signposts there, and you are way above any clouds. When the chute opened, the rest of the jump was anticlimactic because everything had worked perfectly. I landed 12 or 13 minutes later, and there was my crew waiting. We were elated.

JC: How about your right hand?
JK: It hurt. There was quite a bit of swelling, and the blood pressure in my arm was high. But that went away in a few days, and I regained full use of my hand.

JC: What about recent attempts to break your record?
JK: We did it for air crews and astronauts -- for the learning, not to set a record. They will be going up as skydivers. Somebody will beat it someday. Records are made to be busted, and I'll be elated. But I'm concerned that they're properly trained. If they're not, they're taking a heck of a risk.
