Planes have changed a lot since the days of the Wright Brothers (or, perhaps more accurately, Brazilian inventor Alberto Santos-Dumont). Those first wood-and-cloth contraptions are an entirely different species than the sleek Boeing Dreamliners of today. With the continual advancements in aerospace technology, it’s hard to keep up with all the amazing things planes today are capable of doing (and withstanding). Below, 11 airplane facts that might surprise you.<\/p>\n\n\n\n

It\u2019s estimated that lightning strikes each aircraft once a year \u2014 or once every 3,000 hours of flight time. Yet, lightning hasn\u2019t brought down a plane since 1967, due to careful engineering that lets the electric charge of a lightning bolt run through the plane and out of it, typically without causing damage to the plane.<\/p>\n\n\n\n There is no safest seat on the plane.<\/strong><\/p>\n\n\n\n \u0110\u00e2u l\u00e0 ch\u1ed7 ng\u1ed3i an to\u00e0n nh\u1ea5t tr\u00ean m\u00e1y bay n\u1ebfu ch\u1eb3ng may g\u1eb7p n\u1ea1n?

The research revealed that, during plane crashes, \u201cthe seats in the back third of the aircraft had a 32% fatality rate, compared with 39% in the middle third and 38% in the front third.\u201d However, there are so many variables at play that it\u2019s impossible to know where to sit to survive a crash.

To help combat fatigue, some planes, like the Boeing 777 and 787 Dreamliners, are outfitted with tiny bedrooms where the flight crew can get a little shut-eye. The bedrooms are typically accessed via a hidden staircase that leads up to a small, low-ceilinged room with six to 10 beds, a bathroom, and sometimes in-flight entertainment.<\/p>\n\n\n\n The tires are designed not to pop on landing.<\/strong><\/p>\n\n\n\n L\u1ed1p b\u00e1nh m\u00e1y bay \u0111\u01b0\u1ee3c thi\u1ebft k\u1ebf \u0111\u1ec3 ch\u1ecbu \u0111\u01b0\u1ee3c t\u1ea3i tr\u1ecdng 38 t\u1ea5n v\u00e0 c\u00f3 th\u1ec3 ch\u1ea1m \u0111\u1ea5t \u1edf t\u1ed1c \u0111\u1ed9 273km\/gi\u1edd v\u00e0 s\u1eed d\u1ee5ng 500 l\u1ea7n tr\u01b0\u1edbc khi thay l\u1ed1p m\u1edbi.

Additionally, airplane tires are inflated to 200 psi, which is about six times the pressure used in a car tire. If an airplane does need new tires, ground crew simply jack up the plane like you would a car. If the tires fail during takeoff, pilots will abort the flight<\/a> and land immediately for a safety inspection.<\/p>\n\n\n\n There’s a reason why cabin crews dim the lights when a plane is landing.<\/strong><\/p>\n\n\n\n Vi\u1ec7c gi\u1ea3m \u00e1nh s\u00e1ng trong khoang m\u00e1y bay v\u00e0o hai th\u1eddi \u0111i\u1ec3m, \u0111\u1eb7c bi\u1ec7t khi m\u00e1y bay c\u1ea5t v\u00e0 h\u1ea1 c\u00e1nh, l\u00e0 m\u1ed9t bi\u1ec7n ph\u00e1p an to\u00e0n r\u1ea5t quan tr\u1ecdng.

Why? In the unlikely event that the plane landing goes badly and passengers need to evacuate, their eyes will already be adjusted to the darkness. Similarly, flight attendants have passengers raise their window shades during landing, so they can see outside in an emergency and assess if one side of the plane is better for an evacuation.<\/p>\n\n\n\n You don\u2019t need both engines to fly.<\/strong><\/p>\n\n\n\n M\u00e1y bay c\u00f3 th\u1ec3 bay v\u1edbi m\u1ed9t \u0111\u1ed9ng c\u01a1 kh\u00f4ng?

Operating with half the engine power can make a plane less fuel-efficient and may reduce its range, but planes are designed and tested for such situations. Any plane scheduled on a long-distance route, especially those that fly over oceans or through uninhabited areas like the Arctic, must be certified by the FAA for Extended-range Twin-engine Operations (ETOPS), which is basically how long it can fly with one engine. The Boeing Dreamliner is certified for ETOPS-330,<\/a> which means it can fly for 330 minutes (that\u2019s five and a half hours) with just one engine.<\/p>\n\n\n\n In fact, most airplanes can fly for a surprisingly long distance with no engine at all,<\/em> thanks to something called glide ratio. Due to careful aeronautical engineering, a Boeing 747 can glide 17,000 feet (just over three miles) for every 1,000 feet of altitude lost. This ratio gives the pilot more than enough time to get everyone safely to the ground.<\/p>\n\n\n\n There are ashtrays in the bathrooms for a reason.<\/strong><\/p>\n\n\n\n FAA \u0111\u00e3 c\u1ea5m h\u00fat thu\u1ed1c tr\u00ean m\u00e1y bay nh\u01b0ng v\u00ec sao v\u1eabn c\u00f3 m\u1ed9t c\u00e1i g\u1ea1t t\u00e0n trong nh\u00e0 v\u1ec7 sinh?

The reason is that airlines \u2014 and the people who design planes \u2014 figure that despite the no-smoking policy and myriad no-smoking signs prominently posted, at some point a smoker will decide to light up a cigarette on the plane. The hope is that if someone violates the smoking policy, they will do so in the relatively confined space of the bathroom and dispose of the cigarette butt in a safe place \u2014 the ashtray, not a trash can where it could theoretically cause a fire. If you do smoke in the bathroom, expect a massive fine.<\/p>\n\n\n\n That tiny hole in the airplane window has an important function.<\/strong><\/p>\n\n\n\n \u0110\u00e2y \u0111\u01b0\u1ee3c g\u1ecdi l\u00e0 l\u1ed7 x\u1ea3 kh\u00ed, gi\u00fap c\u00e2n b\u1eb1ng \u00e1p su\u1ea5t kh\u00f4ng kh\u00ed b\u00ean trong v\u00e0 ngo\u00e0i khoang m\u00e1y bay.<\/p>\n\n\n\n It\u2019s to regulate cabin pressure<\/a>. Most airplane windows are made up of three panels of acrylic. The exterior window works as you would expect \u2014 keeping the elements out and maintaining cabin pressure. In the unlikely event that something happens to the exterior pane, the second pane acts as a fail-safe option. The tiny hole in the interior window, called a “bleed hole,” is there to regulate air pressure so the middle pane remains intact and uncompromised until it is called into duty.<\/p>\n\n\n\n Airplane environments make food taste worse.<\/strong><\/p>\n\n\n\n \u0110\u1ed3 \u0103n tr\u00ean m\u00e1y bay k\u00e9m ngon so v\u1edbi m\u1eb7t \u0111\u1ea5t?

A 2015 Cornell University study<\/a> found that the environment inside an airplane actually alters the way food and drink tastes \u2014 sweet items taste less sweet, while salty flavours are heightened. Low air pressure can further dull taste and smell, making everything on a plane seem bland. According to a study from the Fraunhofer Institute for Building Physics<\/a> in Germany, it\u2019s about 30% more difficult to detect sweet and salty tastes when you\u2019re up in the air. Next time you fly, skip the meal, and maybe try a glass of tomato juice instead, a drink that tends to taste better in the air than on the ground.<\/p>\n\n\n\n Oxygen masks last for only 15 minutes.<\/strong><\/p>\n\n\n\n C\u00e1c nh\u00e0 khoa h\u1ecdc cho bi\u1ebft, nh\u1eefng chi\u1ebfc m\u1eb7t n\u1ea1 d\u01b0\u1ee1ng kh\u00ed \u0111\u01b0\u1ee3c n\u1ed1i v\u1edbi m\u1ed9t h\u1ee3p ch\u1ea5t h\u00f3a h\u1ecdc, m\u00e0 khi \u0111\u1ed1t ch\u00e1y s\u1ebd sinh ra kh\u00ed oxy.

However, one thing the flight attendants don\u2019t tell you is that oxygen masks have only about 15 minutes worth of oxygen. That sounds like a frighteningly short amount of time, but in reality, that should be more than sufficient. Remember, oxygen masks drop when the airplane cabin loses pressure, which means the plane is also losing altitude. A pilot will respond to that situation by donning an oxygen mask and moving the plane to an altitude below 10,000 feet, where passengers can simply breathe normally, no extra oxygen required. That rapid descent usually takes fewer than 15 minutes, meaning those oxygen masks have more than enough air to protect passengers.<\/p>\n\n\n\n Airplane trails are made up of water.<\/strong><\/p>\n\n\n\n Nh\u1eefng v\u1ec7t tr\u1eafng m\u00e0 m\u00e1y bay \u0111\u1ec3 l\u1ea1i tr\u00ean b\u1ea7u tr\u1eddi ch\u1ec9 \u0111\u01a1n gi\u1ea3n l\u00e0 v\u1ec7t ng\u01b0ng t\u1ee5 h\u01a1i n\u01b0\u1edbc, t\u1eeb chuy\u00ean ng\u00e0nh g\u1ecdi l\u00e0 contrails.
