I think, you know, that there are many myths about aviation and passenger transportation by air. Is not it? Let us work together with you will destroy some of them.
Open plane door during flight deadly
No, not really.
An experienced pilot and blogger Patrick Smith explained that after takeoff the aircraft door are under great pressure. That is, to open this door, you will need the power of Superman. No man, even the world champion in weight lifting is a task beyond the power.
So if you are afraid that to some tipsy passenger during the flight vzbrendit open the door and the passengers will fly over the side, you do not have to worry. It is absolutely impossible.
This myth is closely related to the following:
If the aircraft skin formed a small gap, that through it all passengers can “suck” overboard
The assurances of Patrick Smith, rapid decompression and subsequent crash can cause a bomb blast or substantial structural failure. A small hole in the fuselage – a very different case.
In 2006, when the skin of the aircraft cabin in MD-80 Alaskan airlines the gap was formed, Smith had to make an emergency landing. The pressure really got to go down, but as the drain evenly distributed on the entire plane, nothing critical happened and we had held on to the nearest airport.
The high altitude man gets drunk faster
This myth was disproved “MythBusters.” The level of alcohol in the blood on the ground and in flight, all other things being equal the same. However, since the air on board oxygen is usually less people can really feel drunk, even if does not touch the alcohol.
During the flight, the faeces are released into the air
Stories of the fallen from the sky right on the head excrement – pure fiction. The pilot can not open a sewage tank during flight. If someone’s head fell suspicious substance, the blame is likely to be flown by the bird.
If you click on the sink while sitting on the toilet on the plane, you can get stuck
You can get stuck only in the event that your body forms a perfect air-tight stopper. It is rather difficult. “MythBusters” Adam Savage tried to do the trick, but nothing he did not. But still it is better to wash off while standing.
Constant circulation of the plane ode to the same portion of air leads to the spread of diseases
This myth seems particularly plausible. But Patrick Smith explained that he, too, is wrong:
The air moves in a circle until it gets to the lower compartment, where about half of the weathered overboard. The remaining half goes through filters, mixed with a portion of fresh air and this mix makes a new turn.
Manufacturers Boeing’s claim that thanks to this system, and filters from 94 to 99 percent of all airborne bacteria rendered harmless, and that the air is updated every two or three minutes – much more often than in buildings.
Danger pick up any infection, more likely, may come from surfaces such as folding tables. So it makes sense to take a flight of disinfectant wipes.
Seat belt can reduce your chances of survival in the event of a disaster
Here the situation is much the same as with the seat belt in a car. It is quite possible to imagine a situation where the stuck mount hurt quickly get out of the plane, when suddenly something happened. But in general, benefit from it much more than harm.
Employee-profit Flight Safety Foundation Kevin Hiatt told us about the crash while landing a Boeing 777, which occurred at the airport in San Francisco on July 6:
In such situations, a person can throw out of the chair, hit the hull or drop by another passenger. So it is better to spend a couple of seconds to ensure that unclip than helplessly hanging in the air.
Pilots can control the air flow to keep the passengers in the sleepy and save on fuel.
Patrick Smith called the idea stupid. The oxygen level is determined by the air pressure.
Oxygen masks – it casts intended only to reassure passengers
In fact, in the case of decompression and the crew and the passengers will have to settle out in the cold air, where the oxygen content is quite insufficient. And while the plane did not go down low enough to at least three thousand meters without oxygen masks will not do.
The chances of surviving a plane crash almost zero
