In case you haven’t heard around the water cooler, a window washer fell off a 47 story New York skyscraper and lived. Sure he was hurt – some injuries to his brain, spinal column, ribs, abdomen and multiple broken bones in his arm and both legs, but doctors report a miraculous recovery. According to the New York Post
, he is talking, watching TV, can move all his limbs, has no paralysis and is expected to walk again.
Since this is a construction industry blog from a law firm, first lets discuss his breach of the law of gravity. According to ABC News
, the window washer "fell so far that the force of gravity maxed out and air friction even played a slight role in softening the blow." A physics professor in the article explains that "At a certain point you just don’t go any faster. You hit terminal velocity [124mph]." According to the New York Post article, the window washer was able to hold onto the window washing platform that he was on which likely provided enough air resistance to slow his descent. Newsweek
described the scaffolding platform as 16 feet long and weighing 1,250 pounds. A physics professor in the Newsweek article also hypothesized that the window washer’s platform may have hit the side of the building a few times, slowing momentum. Another contributing hypothesis is possible assistance by a wind current updraft flowing through New York’s forest of buildings. He landed on a pile of twisted cables which is a better cushion than flat concrete.
Next, the window washer’s breach of the law of nature. According to the New York Post article, doctors say a fatality will occur in 50 percent of the falls from three or four stories and a fall from over 10 stories is almost always fatal. A doctor at the window washer’s hospital reports the highest he previously heard of anyone surviving is 19 stories. According to a Slate article, that young man was fortunate to hit a tree on the way down which may have slowed down his fall. So how did this window washer survive? According to Slate Magazine
, the number one body part to avoid landing on is your head; and secondly your pelvic area. Somehow, the window washer accomplished this feat.
Inquiring readers of this blog may want to know if anyone has ever survived a fall greater than 47 stories which is nearly 500 feet. According to a Guardian Unlimited
article, in 1972, a flight attendant holds the world record for surviving a fall, dropping 6.3 miles inside part of a jetliner destroyed in a mid-air bomb attack. A skydiver fell 2.8 miles and only broke his ankle after his main chute got tangled and his reserve chute failed. Clearly, going down with an object – a part of a jet or unopened chute, or hitting a tree on the way down, will slow down velocity. So if you ever find yourself falling a great distance, the Slate article provides a useful tip: "If you're unlucky enough to fall a long distance without anything—like a parachute—to slow you down, it's best to lie flat to increase your surface area in contact with the wind, but be sure to orient yourself feet first before landing."
