What happens if you are sucked from a level?

It would be almost impossible, emissions from aircraft at 30,000 feet survive. Only two of the deadliest followed by a rapid decline of which would be oxygen and extremely cold conditions. People have through holes in aircraft sucked in been, but experienced pilots can store often on the day.

The hole, which last week may have copied through the roof of a passenger aircraft at cruising altitude, expressed for some, to the pilot of the TV show "lost". In this dramatic episode breaks down a plane in the Middle, and go passengers you fly through a gaping hole in the hull.

For passengers on Southwest flight 812, were the consequences far milder: soon after its launch of the Phoenix, an emergency landing, and everyone was the aircraft in order.

But people have through holes in cruising aircraft was thrown in. And an important, if gruesome question: what would happen to you if you were sucked into the atmosphere at 30,000 feet?

The forecast, experts say, would not be good.

"There are a number of critical physiological problems that would be end of life, probably within seconds," said Peter Wagner, a physician and physiologist at the University of California, San Diego. "The fact that you don't forget a parachute." She would be suspended immediately very, very low oxygen levels. "Within three or four seconds is my guess that as hell breathing would be you."

Loss of consciousness and death from oxygen deprivation to the brain would follow soon, next Wagner. At the same time temperature of - 70 degrees Fahrenheit (-57 degrees Celsius) - from the chill wind 500 mph (805 km / H) even colder making-- lead to rapid freezing would starting with the skin, eyes and other surface tissues.

In response to such extreme stress would the nervous system, haywire, which go to potentially deadly spikes in blood pressure and pulse. And the air pressure leads to a bad case of cam cant the sudden change, as if you were diving and came too fast.

Then there is the danger of always popped in the plane on the way to out there, not to mention the trauma of falling.

"You probably cut half or something would hit in that, what you and which part of the body," Wagner said. "All types of images are possible."

Fortunately, incidents like this are extremely rare. Holes are most common in military aircraft, have shaped by bullets or explosives, although civil examples have taken place. In 1988, such as Aloha Airlines flight 243 much lost, if the roof to 24,000 feet. A flight attendant was blown out of the plane and died.

At events such as these the sucking force is cabin environment and which from a difference between the outdoor in print. Aircraft are General in nature, with a pressure similar to what you'd find between 6,000 and 8,000 feet above sea level. At a cruising altitude of 30,000 feet, pressure is lower than what passengers on the inside experience outside of the plane about two and a half times.

If a hole created forms, a strong tendency to compensate a rushing tunnel of the wind, such as the water flows through a tube. In areas of the level, which are far from the hole, possibly winds mild enough just papers to drink.

But air speed picks up as it approaches is a crack, said Geoffrey Landis, a physicist Glenn Research Center NASA in Cleveland. At the point where air by the body passes, it moves at the speed of sound.

Determines the size of a hole, how much air from a level to einmal--could plunge and how dangerous the situation will be. Landis estimate that would make it about 100 seconds for pressure balance through a take a square-foot hole in the body a 747. People sitting next to a hole would this size a half tone of violence against them in the direction of the hole barreling face.

Wind forces begin course work immediately, a hole of any size-extra pressure on the pilot for the aircraft below as soon as possible to increase.

If bad luck "all doomed not to condemn you to end at a level which developed a hole out,", said Landis. In many cases, experienced pilots can react quickly enough to the aircraft safe, as in the recent incident Southwest land.

There are also some things you can do to protect themselves. Keep your seat belt fastened. Put on your oxygen mask. And Wagner proposed that when the hole through something is small as a ball is caused, a book or a magazine hit airline about it.

Air pressure will cement the object through the hole. And you walk away a hero.
