The Safest Seat on an Airplane and 10 Other Airplane Facts You’ve Always Been Curious About


Flying can spark a lot of questions about everything from the iffy food to the holes in the airplane windows. Brush up on your airplane trivia, and become an airplane expert before you fly off for your next trip.


Why is there a hole in airplane windows?



If you've ever been nervous about the little hole in your airplane window, don't fret. The hole is necessary to regulate cabin pressure. Airplane windows are made up of multiple panels, so the hole helps the middle panel from becoming stressed with pressure during flight. Next time you have airplane questions about safety, rest assured that the tiny hole in your window isn't a problem.


Why don't windows and seats always line up on airplanes?



It can seem a little odd that windows and seats don't always line up on planes, but airlines are actually to blame. When the YouTube channel Today I Found Out tackled the subject, it found out that seats aren't placed with any regard to where windows are because the airlines decide how many rows of seats there will be on each plane, and not every airline decides on the same number of rows.

飞机上的窗户和座位常常是不对齐的,这看上去有点奇怪,但是罪魁祸首是航空公司。油管频道Today I Found Out曾就此做过研究,它发现,每架飞机上有几排座位是由航空公司决定的,并且不是所有航空公司都会采用相同的排数,他们安置座位时不会考虑窗户的位置。

Why does airplane food taste so bad?



If eating airline food has left a bad taste in your mouth, you're not alone. When you're that high in the air, your sense of taste dulls, so it isn't necessarily the food's fault. While that may be true, Harold McGee, a scientist and the author of On Food and Cooking: The Science and Lore of the Kitchen, says it doesn't help that airplane food has to be chilled and stored for long periods of time.

如果飞机上的食物在你口中留下了一股坏味道,感觉如此的并不只有你一个人!在高空时,你的味觉会变得迟钝,因此未必是食物的过错。虽然真相可能如此,但是食品科学家哈罗德•麦吉(Harold McGee)说,不可否认的是,飞机上的食物必需经过长时间的冰冻和储藏。哈罗德•麦吉也是《食物和烹调:厨房的科学和学问》(On Food and Cooking: The Science and Lore of the Kitchen)一文的作者。

What's the safest seat on an airplane?



While most airline companies and the Federal Aviation Administration (FAA) maintains that there is no safest seat, a look at hard data about airline accidents from Popular Mechanics found that it's safer in the back. The investigation found that passengers near the tail of the plane were 40 percent more likely to survive a crash than those in the front. So next time you book a flight, you might want to get a seat in the back.

虽然大多数航空公司以及联邦航空管理局(FAA)否认飞机上存在最安全的座位,但是看一看美国科技杂志《大众机械》(Popular Mechanics)的硬数据,你会发现后排的座位更安全。该调查发现,靠近机尾的乘客生还几率比前排乘客高出40%。所以你下次订购机票时,可能会想要选一个靠后的座位。

Why do cabin crews dim the lights when a plane lands?



One of the most unknown facts about airplanes is that cabins dim the lights during landing for security preparation reasons. Dimming the lights is a precautionary measure that allows a passenger's eyes to adjust to darkness. That way, if something goes wrong on descent, everyone's eyes will already be adjusted for evacuation.


What are the white trails that planes leave in the sky?



Those white lines in the sky are called vapor trails or contrails, and they are the result of aviation fuel being burned. When the fuel is burned, it produces carbon dioxide and water, which condenses into tiny droplets behind a plane in the air. If you pay close attention, you can see that there's always a gap between a plane and the vapor trails—that's because it takes time for the gas to form as droplets. The more you know!


Can a plane door actually open mid-flight?



Rest assured, it cannot. In fact, it's actually impossible. The cabin pressure simply won't let you. As explains, "At a typical cruising altitude, up to eight pounds of pressure are pushing against every square inch of the body of the aircraft. That's over 1,100 pounds against each square foot of door."


Is flying in lightning safe?



Flying in lightning is generally safe because planes are built to withstand lightning strikes. The metal from the plane serves as protection, and aircrafts have lightning protection systems to fight electrical build-up. In fact, the safest place to be in an lightning storm is inside a metal cage such as an aircraft. The FAA even estimates that every plane currently in service in the United States gets hit by lightning at least once a year.


Why do your ears pop while flying?



Ear popping can be an unfortunate side effect of flying, but it isn't one that can be remedied easily. Ears pop because when planes get higher in the sky, the surrounding atmosphere becomes thinner. The air inside the cabin, however, is pressurized to a different level, and according to, this causes the air trapped in our bodies (and ears) to expand. While there's no way around this happening, experts recommend chewing gum or yawning to sort your ears out.


Why can't you take a bottle of water through security?



Even the best people at airplane trivia might not know why bottled water is such a no-no in security lines. You can't take a bottle of water through security because it causes both safety and time issues. While TSA security scanners are advanced, they have trouble telling a full bottle of water apart from a bottle of chemicals. TSA allows liquids in small doses, but they have to go through separate from your carry-on luggage.


Why are airplane seats so cramped?



The lack of space in an airplane seat can be boiled down to one word: money. The more people an airline can fit into an airplane, the more money they can make. A study by travel analyst Bill McGee in 2014 revealed that space between seats has actually been reduced over the years. Since 1990, the space between airplane seats has been reduced by two to five inches.

飞机座位之所以空间狭窄可以归结为一个字:钱。航空公司在一架飞机里装的乘客越多,他们赚的钱就越多。旅行分析师比尔•麦吉(Bill McGee)在2014年做的一项研究揭露说,飞机座位间相隔的空间多年以来实际上在逐渐缩小。自1990年以来,飞机座位间的间隔已经减少了2到5英寸。
