Okay, The fastest commercial flight ever was in February 2019 when an airplane flew at the speed of 801 miles per hour, and that was only thanks to the direction it was heading in East And the passengers. They're also rapidly lost weight. What the airplane diet is anything all in due time, though. Here are some mind blowing facts about airplanes. First things first. According to different sources on Lee, 5 to 20% of the world's population have ever traveled by airplane, but all of them have done it more than once. If you're afraid of flying, you must have wondered why planes don't have parachutes on board. Two reasons. Money and common sense first parachutes, air heavy and adding 300 something of them to the weight of the plane would reduce the allowed number of passengers or their baggage. And secondly, even if you have a parachute, you simply won't be able to open the airplanes door to jump out. The difference in pressure is too much, but there's good news to some. Data suggests that sitting in the back of the plane is safer than anywhere else. if you're in the tail here, about 40% more likely to survive in a plane crash, so stick to the back. The only reason you might regret it is if one of your neighbors in the row is sick, not air sex, although that's unfortunate, too. I mean runny nose profit, that kind of stuff. Researchers say such a passenger has an 80% chance of infecting everyone around them with whatever they have to minimize that risk, turn on the little air vent above your head and direct its flow on yourself. It will work as an air shield, flowing away the germs and not letting them cling to you. Hey, wouldn't it be great if you could buy a cheap little HAZ mat suit from the flight attendant during the trip? Oh, but then you have to crawl into the thing while in that cramped little seat as your seatmates wonder which one of them you're dissing? Guess not, huh? But don't be an arrest of blame. Your coughing neighbor. If you get sick after the flag, ask yourself first. Did you take the blanket from the flight attendant? If so, you might have caught germs from that airplane crew members say they only washed blankets once every few days, and the rest of the time they only get folded and reuse. Who knows who used yours before you and for what? Yuck. Unlike the cabin doors, the bathroom actually can be open. From the outside, There's a hidden latch that allows flight attendants to unlock the door in case of emergency or example to rescue a passenger who faded inside. No, they don't do it for fun. Ever heard that banging noise when coming on or exiting the plane? Yeah, it's not the ground crew hurriedly repairing the play. It's just the baggage being loaded or unloaded. Workers don't really throw it around, either, but they usually have very little time to be too gentle. If you fly safe from New York to London and not the other way around, consider yourself lucky. You'll probably be there a couple hours early, and that's true for many planes flying East Nature itself helps them. There are jet streams high up that, if used correctly, give a hefty speed boost to aircraft. Jet streams air basically constant high speed streams of air that carry you eastward on their gentle wings. Ah, then you arrive early and there's no gate for you yet, so your plane sits on the tarmac waiting. You also might want to step on the scales while traveling with the jet stream because they'll probably show a rather pleasing number, thanks to the e o vos effect. Perceived force of gravity is less when you're moving east, which means you weigh a tiny bit less to the bad. News is as soon as the plane lands and stops, the pounds will come back, thanks to international airspace agreements, planes flying from the US too far and Middle East travel over the North Pole, and you can see it's stunning, icy landscapes pretty close. That's because airplane fuel freezes at temperatures below 50 F and the aircraft needs to get much lower than its cruising altitude. For warmer air. Make sure to get a window C. Another sightseeing tour happens when your plane suddenly decides to not land straight away, but make a circle around the airport. This can occur when there's something on the runway or the wind is too strong or there's just a heavy traffic down below. Yeah, airplanes also have traffic jams. So look outside and enjoy the panorama. That is, if there is a window near euro. Originally, planes were designed to have seat rows aligned with the windows, but to squeeze more people inside the cabin and make tickets cheaper. Most airlines decreased the gap between the rose and the economy class, so your window seat should be more properly called a wall seat. Now, if you want to complain about that, you can come up to the pilot yourself. Just make sure you know the code from the cockpit door. In fact, no one can enter the cockpit without the pilots say so. Even if you have the code, the door will only open after about half a minute. And that's if the pilots don't react. They could deny entrance by simply pressing a button. But let's imagine you've somehow gotten inside the cockpit and the pilots are not there. Oh, can a regular person land a plane in such a situation like they show in the movies? Sorry, Highly unlikely. Still, if the plane is modern, all its systems are intact and there's at least one flight attendant on board. They might be ableto land the aircraft following the instruction from air traffic control. Wait a second. There's an autopilot in there. Can it land the plane by itself? No good there, either. Even more. The autopilot doesn't even fly the plane proper. It's basically just a super advanced GPS that's only taken into account the plane's route and surroundings. You can keep the machine in the air, but any complex action is a human pilots responsibility. That's why autopilot can on Lee take control at the cruising altitude, which is usually around 36,000 feet. Planes have to fly so high to reduce air resistance because his drag and reduces efficiency of the engines. It shouldn't climb too high, though, because it will eventually lose lift and drop down, as they say. Yeah, speaking about control, the pilot is actually in charge of everything during the fly. Their level of responsibility is enormous, so they're both law and its enforcers On board. They even have handcuffs to tame unruly passengers. So behave, will you, so that you understand what kind of responsibility is in the pilot's hands. A Boeing 7 47 airplane consists of numerous parts like about six million of them. Just imagine navigating this kind of complex machinery with just a couple of buttons and levers. No wonder pilot has to go through rigorous and lengthy training before being allowed in the cockpit. Even their oxygen masks are different from those in the cabin. While a regular passenger mass on Lee has enough oxygen for 12 to 15 minutes, the one in the cockpit is designed to last much longer. That's because of that same huge responsibility. Pilots have to stay awake and focus to save all those lives on board at all costs. And if you think smaller private planes air safer than big commercial ones, that's a myth. According to statistics, passenger airplanes are more than twice safer than private ones exactly because of the amount of rules and regulations imposed on pilots follow strict schedules and are trained professionals. While private planes are often flown by amateurs on the topic of amateurs, some believe that hard landing on water should be safer than on the ground. But that's not true either. Pilots even say that they try to avoid landing on the water is called ditching by all means. Because of its structure, water is actually harder than soft ground at the moment of impact. And when the plane falls, it'll probably be filled with water very soon, the crew has to act really quickly to get everyone to safety after such a crash. Landing and crash landings are exactly the reason why you have to stow your tray table and get your seat in the upright position in case of a hard impact and open tray may injury. And if your seat is recline, your head will travel a longer distance to the seat in front of you, increasing the risk of head trauma. It's for your own safety pal, but at least you'll enjoy the pleasant blue color of that seat. It's made so to calm you down, psychologists say the color blue helps you relax. If the seats were red, for example, that could have gotten on your nerves and made those who are afraid of flying even more jittery. Who and finally, the most important question. When are those mysterious numbers on your boarding pass your name, gate and flight number? Okay, that's clear. There's a six letter passenger name, reverence or record locator. It's randomly generated for you personally and gives access to your passenger data to authorities. And then there's a standalone letter depicting your class A or F for first. Why? For economy and cue for economy discounted flight. Hey, if you learn something new today, then give the video alike and share with a friend. And here's some other videos I think you'll enjoy.
