Okay lets deal with it. Some of the stories you’ve heard are true, but most of them are fables. here are some of the most common misconceptions about flying .

1At high altitude people get drunk faster


This myth is refuted "MythBusters." The level of alcohol in the blood on the ground and in the plane, or any other place is equal and the same. However, since the air on board is usually with less oxygen, a person can really feel drunk, even if he has not touched alcohol.

2Opening the door of the aircraft during flight is extremely dangerous


Not really.
An experienced pilot and blogger Patrick Smith explained that after taking off the doors of the aircraft are under great pressure. That is to say, to open a door, require the power of Superman. No man, even the world champion in weightlifting, cannot do this task. So if you are afraid that if some drunken passenger during the flight attempt to open the door and the passengers will fly over the side, you do not have to worry about anything. This is quite impossible.

3Formation of a small gap or a hole on the aircraft, will lead to everyone being sucked right out.


On assurances Patrick Smith, rapid decompression and subsequent crash could cause an explosion or bomb material structural failure. A small hole in the fuselage - a very different case. In 2006, when the breach, Smith had to make an emergency landing in the skin of the aircraft cabin MD-80 Alaskan airlines. The pressure was really fall, but since the leak spread evenly throughout the plane, nothing critical has happened and we are well have lasted to the nearest airport.

4During the flight, the feaces are thrown in the air


Heard stories of excrement falling from the sky right on a guy's head? - pure fiction. The pilot can not open the tank with sewage during the flight. If someone on the head dropped a suspicious substance, the blame for this is likely to have to flown by the bird.

5If you click on the sink while sitting on the toilet in an airplane, you can get stuck


While the sound of a toilet plane flushing is loud and disconcerting, you won’t disappear down the tube if you push the button while sitting down But still its better to wash standing.

6The constant circulation in the plane ode and the same portions of air leads to the spread of diseases


This myth seems especially plausible. Air moves around until it enters the lower compartment, where approximately half disappears overboard. The remaining half passes through the filters, it is mixed with the fresh air portion and the mix makes a new turn. Manufacturers Boeing's claim that thanks to this system, and filters from 94 to 99 percent of all bacteria in the air is neutralized, and that air renewal takes place once every two or three minutes - more frequently than in buildings.

7The chances of surviving the crash are almost nil


At the time of the disaster the same Boeing 777 in San Francisco, rescued 304 of the 307 passengers. In addition, according to the US National Transportation Safety Board during the incidents during passenger flights of 1983 po2000 year survived 95 percent of the passengers of these flights. The term "incident" refers to all the cases that have led to major aircraft damage, death or injury of passengers.

8The seat belt can reduce your chances of survival in the event of a disaster


Here all is about the same as with the seat belt in the car. It is quite possible to imagine a situation when stuck fixing interfere quickly to get out of the plane, if something happen. But in general, one benefits from it much more than getting harmed. In such situations, a person can be thrown out of the chair, hit on the body or throw on another passenger. So it is better to spend a couple of seconds for it to detach than helplessly hanging in the air.

9Pilots can control the airflow to keep passengers sleepy and save on fuel.


Patrick Smith called the idea completely stupid. "The idea that we cut back on oxygen is simply ridiculous. Oxygen levels are determined by pressurization."

10Oxygen masks are intended only to calm the passengers


In fact, in the case of decompression and the crew and passengers will have to be content with air overboard, where the oxygen content is totally inadequate. And while the plane falls low enough, at least up to three thousand meters, will not do without oxygen masks.

So, now you know.
