11 thing you do not know about aircraft ..

It is estimated that lightning strikes every aircraft once a year, or once per 1000 hours. However, lightning has not fallen since 1963, because of the precise engineering that allows the electric charge to get out of the plane without Causing serious damage.

1. There is no safe seat on the plane: Although studies of aircraft accidents have shown that the mid-seat seats on the plane are the lowest rate of death, there are many variables and it is impossible to know where we sit to survive during the crash.
   3 - Some aircraft have secret crew bedrooms: On long flights the crew can work for 16 hours, so there are some aircraft, such as Boeing 777 and 787 Dreamliners equipped with small bedrooms where the crew can get a little rest.
   4 -The tires are designed in a way that does not make them popping on landing. The tires are designed to withstand a weight of 38 tons and can drop at 170 mph, about 500 times more than before. Pressure used in car tires.
   5 - Why the light is lower when landing: If the plane landed badly at night and passengers need to evacuate, light is reduced to adjust their eyes with the dark so it is easier to move inside the plane full of obstacles and seats.
   6-The aircraft does not need all the engines to fly: the idea of ​​a plane crash from the plane in the middle of the flight looks scary, but every commercial plane can fly safely with only one engine, but flying with only one engine can make the aircraft less fuel efficient and can reduce As well as their scope, so aircraft are designed and tested better for such situations. In fact, most aircraft can fly surprisingly long distances without any engine at all, thanks to the sliding ratio and precision aeronautical engineering.
   7-There is an ashtray for cigarettes in the bathrooms: The Federal Aviation Administration has banned smoking on airplanes for years, but despite the non-smoking policy and countless smoke-free signs, at some point the smoker will decide to light a cigarette on board and if done, Bathing and safe disposal of cigarette ends There is an ashtray for cigarettes, and their absence can cause a fire.
   8 - the small hole in the window of the aircraft: Most windows of the plane consists of three panels, the outer window and the function of maintaining the pressure of the cabin, but likely to happen something to the outside, and the second part to support the first part, the small hole in the inner window is to regulate air pressure .
   9 - Why the food is bad: A study from Cornell University in 2015 found that the interior of the plane actually changed the taste of food and drink, it makes the sweet taste less sweet and increase the taste of salty flavors, because of the dry air recycled inside the cabin as well as the humidity Few.
   10 - Oxygen Masks: These masks lose their oxygen after 15 minutes, but do not worry, this time is enough because the plane needs less than 15 minutes to be at 10,000 feet or less, the right height where you can breathe naturally without oxygen masks. .
2. Why the planes leave behind white lines in the sky: those white lines are simply because of the condensation process, where the aircraft engines produce water vapor as part of the combustion process, and when this hot steam is pumped from the exhaust of the plane, These lines are white.
