resistance 359 The man who will free-fall to Earth From over 130,000ft, the ultimate parachute jumper will break the sound barrier while on his way down Caroline Davies May 25, 2008 For twenty years Michel Fournier has been planning an amazing adventure. He is planning to fly to the edge of the Earth’s atmosphere. There he will experience the weightlessness and deep blackness of space, look down at the Earth – and then jump. Now the 64-year-old retired French army officer is finally going to live that dream. Today, if the weather is good, he will attempt a parachute jump from almost 25 miles (40 km) above Saskatchewan in Canada. Fournier will sit inside the pressurised gondola of a 650ft balloon and make a two-hour journey up to 130,000ft (nearly 40,000 metres). Then, wearing only a special spacesuit, helmet and parachute, he will jump out of the gondola and fall back down to Earth. It will take 15 minutes and he will travel at speeds faster than the speed of sound. It is extremely dangerous and he might die. At 40,000ft there is not enough oxygen to breathe and he could suffer an embolism, which would kill him. At a height of 12 miles above the Earth, if there is a problem with his spacesuit, his blood might start to boil because of the air pressure. If his skin becomes open to the air, he will lose consciousness and suffer brain damage within a few minutes. But if he succeeds, he will break four world records, falling longer, further and faster than any human has ever fallen before. “It’s not a question of world records,” he said from his base in North Battleford. “What is important is to see what the results of the jump are and if it can help to make space travel safer. But the main question all the scientists are asking is, can a man survive when travelling faster than the speed of sound?” Fournier used to be a paratrooper. He has been preparing for this jump for 20 years. In 1988 the French space agency wanted someone to free- fall and parachute from the edge of the Earth’s atmosphere to test possible methods of escape for astronauts. After physical and psychological tests, they chose Fournier but then they stopped the programme. So he decided to do it himself. He sold his home and most of his belongings and tried to raise the $20m he needed for training and equipment. He has tried twice before, but bad weather or technical problems stopped him getting off the ground. But from today there is a small window of opportunity when the weather conditions are perfect and Fournier and his 40-strong team want to use that opportunity. Fournier will breathe pure oxygen for two to three hours before take-off to prevent decompression sickness. He will then rise in the giant balloon to the edge of space. Then the pressure will gradually decrease to allow him to make his jump. He will be in free-fall for around eight minutes and will be travelling faster than the speed of sound (770mph) inside 40 seconds. He will continue to a speed of around 1,000mph. At lower altitude, wind resistance will slow him down and his parachute will open at around 20,000ft. If he succeeds, he will break records for the fastest free-fall, the longest free-fall, the highest altitude for a human balloon flight, and the highest parachute jump. The previous record jump from a balloon was in 1960 by Joe Kittinger, now aged 79, a former US Air Force pilot who jumped from 102,800ft and travelled at more than 600mph. He has been writing to Fournier. “I told him many years ago, it’s definitely beautiful but very dangerous. If there is a problem with the spacesuit, you will die,” he said. Fournier is not the only man who is trying to break the records. Steve Truglia, a 45-year-old stuntman from London, is planning to jump from an even higher altitude than Fournier in July. Jean Harel, a member of Fournier’s team, says that he believes Fournier will succeed. “It is impossible not to be involved in this dream, no matter how difficult it seems.” Download 7.3 Mb.
