The odds of surviving a 6-mile plummet are extra ordinarily slim, but at this point you’ve got nothing to lose by understanding your situation. There are two ways to fall out of a plane. The first is to free-fall, or drop from the sky with absolutely no protection or means of slowing your descent. 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. That classification means you have the advantage of being attached to a chunk of the plane. In 1972, Serbian flight attendant Vesna Vulovic was traveling in a DC-9 over Czechoslovakia when it blew up. 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. Surviving a plunge surrounded by a semiprotective cocoon of debris is more common than surviving a pure free-fall, according to Hamilton’s statistics; 31 such confirmed or “plausible” incidents have occurred since the 1940s. Free-fallers constitute a much more exclusive club, with just 13 confirmed or plausible incidents, including perennial Ripley’s Believe It or Not superstar Alan Magee—blown from his B-17 on a 1943 mission over France. The New Jersey airman, more recently the subject of a MythBusters episode, fell 20,000 feet and crashed into a train station; he was subsequently captured by German troops, who were astonished at his survival.
