The sky diver tosses his chute from the plane and then jumps out after it, waiting as long as possible to retrieve it, put it on and pull the ripcord. The ultimate learn-by-doing experience might be a lesson from Japanese parachutist Yasuhiro Kubo, who holds the world record in the activity's banzai category. Martial arts were deemed especially useful for hard-surface impacts: "A 'black belt' expert can reportedly crack solid wood with a single blow," the authors wrote, speculating that such skills might be transferable. The same study noted that training in wrestling and acrobatics would help people survive falls. But a 1963 report by the Federal Aviation Agency argued that shifting into the classic sky diver's landing stance-feet together, heels up, flexed knees and hips-best increases survivability. A 1942 study in the journal War Medicine noted "distribution and compensation of pressure play large parts in the defeat of injury." Recommendation: wide-body impact. The question of how to achieve ground contact remains, regrettably, given your predicament, a subject of debate. This adds friction and helps you maneuver. Spread your arms and legs, present your chest to the ground, and arch your back and head upward. To slow your descent, emulate a sky diver. With a target in mind, the next consideration is body position. Hitting the ocean is essentially the same as colliding with a sidewalk, Hamilton explains, except that pavement (perhaps unfortunately) won't "open up and swallow your shattered body." Contrary to popular belief, water is an awful choice. Hamilton documents one case of a sky diver who, upon total parachute failure, was saved by bouncing off high-tension wires. Hitting the ocean is essentially the same as colliding with a sidewalk. Body meets Windy City sidewalk in 12 seconds.įrom an airplane's cruising altitude, you'll have almost enough time to read this entire article. Equal speed means you hit the ground with equal force. You max out.ĭepending on your size and weight, and factors such as air density, your speed at that moment will be about 120 mph-and you'll get there after a surprisingly brief bit of falling: just 1,500 feet, about the same height as Chicago's Willis Tower. When downward force equals upward resistance, acceleration stops. But like any moving object, you create drag-more as your speed increases. As gravity pulls you toward earth, you go faster. Whether you're attached to crumpled fuselage or just plain falling, the concept you'll be most interested in is terminal velocity. The New Jersey airman fell 20,000 feet and crashed into a train station he was subsequently captured by German troops, who were astonished at his survival. Surviving a plunge surrounded by a semi-protective cocoon of debris is more common than surviving a pure free-fall, including perennial Ripley's Believe It or Not superstar Alan Magee-blown from his B-17 on a 1943 mission over France. She fell 33,000 feet, wedged between her seat, a catering trolley, a section of aircraft, and the body of another crew member, landing on-then sliding down-a snowy incline before coming to a stop, severely injured but alive. In 1972, Serbian flight attendant Vesna Vulovic was traveling in a DC-9 over Czechoslovakia when it blew up. That classification means you have the advantage of being attached to a chunk of the plane. The second is to become a wreckage rider, a term coined by Massachusetts-based amateur historian Jim Hamilton, who developed the Free Fall Research Page-an online database of nearly every imaginable human plummet. The first is to free-fall, or drop from the sky with absolutely no protection or means of slowing your descent. There are two ways to fall out of a plane. Granted, the odds of surviving a 6-mile plummet are extraordinarily slim, but at this point you've got nothing to lose by understanding your situation. The ground, after all, is your next destination. When that happens, remember what you are about to read. You'll be unconscious soon, and you'll cannonball at least a mile before waking up again. Believe it or not, you're better off up here than if you'd slipped from the balcony of your high-rise hotel room after one too many drinks last night. (Yes, it goes beyond surviving the destruction of your aircraft.) Although gravity is against you, another force is working in your favor: time. But now's the time to focus on the good news. There's cold air rushing everywhere, and sound. Not long after takeoff, you drift to sleep. You have a late night and an early flight.
