Shout out to the guy on the bridge who was has been waiting his whole life to be interviewed about these exact questions, and whose kid was bored out of their mind
lol watching Veritasium's videos always makes me wish I could be one of the people he asks about things because I often know just enough about these surface level things he asks to answer them correctly. Farts and taste I wouldn't have gotten (I would've answered yes to the former and told him it was only because he was saying it himself though lol), but the rest I more or less knew.
@@mirzaahmed6589Just being a planespotter in and of itself won't really give you that much knowledge, you'd probably just know how to identify different aircraft types. The group of non-professionals that knows the most is probably flight simmers. At least those that take it seriously.
@@iaexo As somebody who's played War Thunder and seen a fair amount of sim videos, I actually knew about all these except the food segment. I hope that some day I'll be in the majority of airplane enthusiasts instead of the minority. So many fascinating things about aircraft beyond just their looks.
An aircraft mechanic here, One of the many reasons we pump in dry air and reduce moisture content in the aircraft cabin is because water molecules present in the air will freeze into small ice blocks at high altitude which will damage a lot of the pneumatic system components including important pressure regulating valves and possibly block filters leading to blockages.
Do you even need to remove any more moisture? The outside air is extremely cold, so just warming it up should reduce the relative moisture level (relative to what moisture the air can hold at that temperature) significantly. Or is that something you only do while on the ground / close to the ground?
@@BunjiKugashira42 You're correct. They don't remove any moisture. Within the engine, as it gets compressed, the air warms up. Ice is still a concern though, but it's mainly on the leading edges of the plane. Such as the wings, because it could disrupt airflow/cause turbulence, or the first stage or two of engine blades. There it's handled by simple electric heaters.
@@zrora4385 So that explains the ice separators in the A/C ducts.?That's the rattling sound you occasionally hear above your head. But you're correct , in that at cruise altitude this is not a big problem.
What? The engine doesn't get to choose how humid the air is it inhales. And after two stages of compression, the air is not cold anymore but actually too warm for the cabin and needs to be fed through the AC packs. So there's no icing risk from cabin air.
@@BunjiKugashira42 Yeah, at first I thought well unless the pneumatic system gets the working fluid (the air) into the temperature even lower than before. But considering the air outside is -50 C, that doesn't sound normal.
@@LuisGustavoBDthe greatest sadness when I watch these videos is I know we get such a selection bias so we have no idea how many people actually knew or not.
I always wanted to say how much I respect the decision of putting the ad last. It shows that you actually respect your audience and the respect is mutual.
Yes of course. But it's fun to hear him say "... we specifically asked ground news to sponsor this video." Meaning: Veritasium, with his 16M subscribers, gets to pick and choose who he'll allow as a sponsor, and then he'll stick them at the end of the video. Must be nice.
You can't watch or even scan past an add for the 100s or 1000s of hours Derek and his team put into making the content. You don't pay a cent. Who cares where he or any other creator puts it. This is their job, and it costs money to make. Total L take.
I was in a DC-8 at age eight. I discovered the little wheels in the arm rest and started to play with them. Almost immediately the cabin announcement system said "someone has moved the radar detector" and I sat stock still for the next 6 hours. It took me 30 years to reason that the radar deflection could not have been my fault
Same. I was just thinking about how it's been a few days since I watched a Mentour Pilot video, and then boom, he's in this one. Great collab, in my opinion.
I remember watching some old science documentary about people living in a pressure chamber under water because the pressure was far more than one atmosphere. They complained that their carbinated drinks lost their fizz, the only flavor that didn't go bland was spicy food, and they had to be careful heating drinks because the temperature water boiled had increased. I know it's kind of the opposite of what happens on planes, but I just find it interesting that our sense of taste is so dependent on atmospheric pressure.
Wouldn’t the drinks remain super fizzy? Part used bottles go flat because the bubbles come out until they re-pressurise the bottle itself. Just a thought
There is a short clip where Chris Hadfield (Canadian Astronaut) shakes a can of Coke and immediately opens it... and nothing happens because he and some others were in a high-pressure underwater structure.
@@FirestarterAJ12 The reason it tastes fizzy is because the bubbles are forced out of the liquid from the comparatively low pressure of the atmosphere than the inside of the can. If the atmosphere is closer in pressure to the can, there will be less bubbles and less fizz.
As an aersopace engineer with more than 20 years working in aircraft development, I feel so glad to see a video like this. Factual and to the point. Great job!
My friend told me what we saw in the video, is a bit (30-40years) outdated info. Today engines operate cheaper at lower altitudes, at cruise altitude the fuel consumption is greater.
@@dornyeilaszlo Your comment is well-intentioned but only an opinion, and like our southern outlet, we all have one that blasts smelly hot air. If you can provide a reference that clearly supports your idea, it might be worth reading. Thanks for your interest and contribution.
The ISS actually expands and contracts also every time it orbits due to thermocycling from exposure to the sun and space. That's one of the main reasons why space stations have a limited life.
Good point. At the same time, an insulation must exist. So the question becomes is the same structure responsible for maintaining thr pressure also subject to these temperature changes
ISS circles the Earth in roughly 90minutes. Going as high as 250 degrees F (121 C) on the sunny side and as low as -250 degrees F (-157 C) on the dark side. So it has more circles on expand/contract that you can imagine.
PETTER! So happy to see Mentour Pilot getting some love. His channel took me from extreme flight anxiety in 2016 to a regular flier who, gasps, enjoys it! I love learning more and more about flight/planes, it has opened up the world for me.
Same here. 20 years without flying. I promised a friend I would go with her to Ireland. Also because Ireland is an amazing place and Irish people are incredibly nice, but first and foremost to go with my friend... So I booked a refundable ticket (yeah, not so brave...) and started watching videos about planes just to have perfect excuses to cancel the trip, because I was so afraid. I ended up on Petter's channel. No sensationalism, no overdramatisation, just a professional and detailed look on every accident, with a focus on what ended up being updated, changed, bettered... I wouldn't say I love flying (it there's a reasonably longer train ride instead, I'll gladly choose it!), but I'm way less afraid of flying now.
@@BD-nt3ee this is fantastic and I’m proud of you. It wasn’t easy, but you did it and you allowed a professional to give you real facts to start counteracting the ones our brains come up with on their own. If anyone ever asks about my journey or mentions they have similar fears, I go out of my way to recommend Mentour Pilot.
@@MrHungrySimon at nearly every station on the Stockholm commuter train network they announce "please press the button to open the door when it's green". There are 3 stations in the very central areas where you don't need to, so how people are so stupid that this needs to be announced more or less everytime..... Smh.
If noise would boost tomato juice consumption, it would be a very popular club drink, which it is not. I think apple and tomato juice are popular because they are not carbonated. Carbonated drinks fizz different because of the lower cabin pressure.
The tomato juice connection! That's wild! I do happen to drink it on the ground as I'm a natriophile, but I do order it more often on a plane than most other beverages. Cool to know why!
I’m incredibly gassy when I fly. I fart like no other; and they’re always so forceful. It’s as if my trumpeting ass finally decides to have a personality and wants to chat. It’s also often smelly. So on long haul flights, I’d tuck myself on all sides with the blanket. I’d often not allow my other end from talking by stretching out that starfish butt hole as much as possible as to reduce vibrations; so only forceful puffs of wind comes out. I’d then immediately dip my head into the blanket and breathe in as much of the stank as possible so others won’t be able to smell it. I’ve yet to have people complain next to me about farting in the decades I’ve been flying for my job.
I've always absolutely loved Mentour Pilot's channel! I still remember the day I found it I binged it for many days. The amount of technical details that Petter makes easy to digest allowed me to get a little bit into aviation I never thought I would
I can relate! I was doing a lego ISS when I first came across his channel and have seen every accident breakdown since. You couldn’t have said it better. He’s the only reason I got Microsoft Flight Simulator 😅
Similarly to some of the other comments, I studied Aeronautical engineering for four years, worked for Rolls Royce jet engines in the defence aerospace sector and been an airline pilot now for 12 years. I’ve loved Veritasium videos for years and this just proves to me how well researched these videos are. Thanks for all your effort, accuracy and clarity!
I am an airline pilot and simulator instructor for a major airline. You nailed it! You hit all the little things on the head and covered the common misconceptions I see from pilots themselves. Going to send this video to future students.
E ven a 10-year-old or a 12-year-old should be able to deduce from first principles why a jet plane flies at 30,000 ft to 40,000 ft and the reason primarily they fly that high is because of less aerodynamic drag due to the lower density of air. So that you can for the same amount of thrust , you use less fuel, And still be able to maintain enough velocity to achieve lift for that altitude. ( Also, jet engines are designed to work at maximum efficiency around that altitude, Also flying above turbulence but these are secondary reasons).. Also the reason you cannot open doors is because of the pressure difference. While interior of a jetliner is pressurized to one atmospheric pressure. The pressure outside is much lower due to the altitude and air density it's flying at .A reasonably smart 10- 12-Year-Old should be able to deduce this from first principles!. Are majority of people idiots? So why don't planes fly even higher than $30 or 40,000 feet, for even lower aerodynamic drag at the lower air density at higher altitude? Reason is yes, your aerodynamic drag will drop even further, but the velocity requirement that would be required to generate enough lift in the thin air of the higher altitude would also increase, needing greater thrust. It is sort of a u-curve. And 30 to 40,000 is usually The Sweet Spot for maximum efficient fuel efficiency. Also, there needs to be like a greater degree of pressure frame structural stresses that you need to protect against because of the greater pressure differential at the higher altitude (interior of a jet is always pressured to one atmosphere, while beyond 30 to 40,000 ft outside pressure is even lower). Also, jet engines are designed for maximum efficiency at certain altitudes windows. For these various reasons, 30 to 40 000 ft is The Sweet Spot. Anyway, I don't expect a 10 or 12-year-old to figure out the this part, but the original point I made should be evident and should be able to be deduced from first principles..
@@aryangod2003 I do agree this seems to be mostly basic knowledge that even a child would know. However I have come to the understanding of acquired knowledge supersedes the old common sense approach. An excellent example is slippery when wet signs, or even 1st year apprentice on their first day. I feel it's better to acquire knowledge and not just believe you know it already. This in turn avoids accidents. For instance, I knew planes go higher to save costs (along with safety of concerning lower heights plus noise). I understood the air was 'lighter' or thinner, so obviously less resistance. But I didn't have all the tech associated with it, or the exact reason why it's 30,000 and not 25,000. Clearly the atmosphere and even the Earth's circumference is valid. I basically have never acquired this knowledge (no need to learn). And my common sense towards it may even be mistaken!
@@aryangod2003the major reason why commercial flights cannot go much higher than 40kft is because of air density is well, since at higher altitudes the engines will lack the oxygen (cecause of very low O2 density) so the fuel wont be able to ignite properly. Some Military airplanes’ engines are designed a bit diffrently and they can support flights up to 70-80kft
That Hawaiian flight that blew the roof off, is where Vampire Weekend got the name from their album, ‘Only God Was Above Us’ from a quote in a newspaper after that incident.
Talking about "What Everyone Gets Wrong About Planes", I'm still sometimes thinking about those poor people who clung to a departing American plane in Afghanistan Like, incoming winds of 900km/h, -50°C, pressure so low that you can't breathe, no place to get a grip, etc I know they most likely didn't know all that stuff but it's fascinating and terrifying how people thought they could survive it
It's not that the people thought they could survive through it It's more about the people scared about living through what's happening on the ground that they were trying to escape And we all know the human brain doesn't stay fully rational in face of anxiety like that
I’ve drank tomato juice and added pepper in hundreds of Lufthansa flights over the years. Every time i bought it at home i never felt like it. Thanks a lot for revealing one of my most random life mysteries 😂
My favorite two channels in one video? I must be dreaming. I was scared of flying but watching Mentour Pilot allowed me to go through turbulence without even paying attention to it. Thanks Derek for this video.
I remember in the 90's taking a flight from Reykjavík to Miami and listening to my fm radio as we travelled down the east coast. The channels were clear-ish and gently passed from one to another, music and news all mixed up. It was lovely...
Thank you for having Petter (Mentour) on your channel. He is one of the best aviation channels, if not the best, out there! Awesome collaboration, its like suddenly bumping into an old friend. Very pleasurable surprise!
Slightly unrelated... as a truck driver... I recently undid a lugnut on a trailer wheel hub, by hand... This means, the last guy had a retorque notice that he chose to ignore (or lost and forgot)... and a tire could have come off within a trip or two (while at highway speed.) It's a good thing the aviation industry is held to such scrutiny... much more so than the ground transportation industry. We... on the ground... have a long way to go. Truckers are always whining about 'restrictions' and 'inspections'... but how many of my 'co-workers' actually 'do their required pretips thoroughly?' Some just sign off as good without checking anything (I've even seen trainers doing this...)
@@Moto848 boeing kinda proves the regulation isnt enough.... no one should be dying to some company's laziness to redesign their plane for the new electric motors they want to install
Many industries have policies "written in blood". An FYI for anyone reading who hasn't come across the term. It means the rule exist because someone died to motivate it
Interesting what people knew about the subject, but you brought back very vivid memories when you talked about plane food. While serving overseas during the war as an aircraft technician. Civilian airlines were used for troops. On board, they were fed the same way civilian are feed. It wasn't that way for us on the ground. You can imagine what we had to eat. So when one landed, many technicians ran to prepare the plane for departure. Except we didn't go right to work doing that... we went straight for the kitchen and left over meals in the warming trays. It was just one of those things that brought a sense of home to out tummies !
Got curious today and checked when I subscribed to the channels I watch and was surprised to see Veritasium as my longest subscription. Can't believe it's been over 7yrs now and the content just keeps getting better
Hearing the magic word of the question instantly activated the answer area of his brain, he must have experienced some unforgettable unpleasant moments on a plane 😂
The plane door pressure differential reminds me of a large reach in freezer with fans that create a partial vacuum after closing. You can't open the doors no matter how hard you try.
As an aerospace engineer with over 20 years experience and someone who manufactures door lock actuators, the doors are actually locked on certain airplane models (i.e. Boeing 777). Flight lock actuators lock the doors of an aircraft when the weight-on-wheels signal is false (meaning the aircraft is not on-ground). This actuator moves a pin/rod into a locking meachanism effectively locking the door while in flight.
@@niconico3907 No, the logic for the doors is such that it would be unlocked in an emergency. From memory, on the B787 one engine has to be running and airspeed above 80 knots for the lock to engage. Its de-energised to unlock with no electrical power.
Literally never had tomato juice beverage in my life except on long flights. I was so surprised by the amazing taste but on the ground literally never felt like even finding one to drink. When you asked that question I was like Tomato juice for me but amazingly that's the answer!!!
I've never had tomato juice on a flight, simply because it's not a drink that I normally have. However, on the next flight, there's some experimental science to be done, I can see!
Yessss! Love the collab with Mentour Pilot (my girlfriend and I absolutely binge his content)! I think every once in a while it should be highlighted just HOW incomprehensibly safe civil aviation has become, and how diligent those authorities, training infrastructures, airlines and pilots are - especially compared to the absolute insanity of car traffic that many people hardly think about. Even a Boeing 737 MAX before the redesign of the terribly flawed MCAS was statistically safer than the average car ride.
That's always been an interesting comparison. Everyone is driving themselves, definitely don't do anything like a pre-flight, encounter obstacles constantly, and don't have autopilot (mostly). I wonder if you could control for those variables
Derek and Petter are two channels I have really enjoyed independently, never would have thought of a collab but both of you are great educators and it worked really well.
It's not about talking, it's about 200 watts of radio interference at sub-1 GHz long-range frequencies due to phones trying to ping cell towers at max power each.
@@PredatoryQQmber Don't think you watched the whole video. @dustinsullivan7216 was referencing that the EU is trying to make calls on planes a normal thing. Also they pointed out that phones don't cause interference.
@@jackchandelier I don't think you've read my whole comment. I was referring to the nature of radio signals, which I, apparently, know better than either you or the professional yapper in the video. In fact, they even said in the video itself for the likes of you that standard 1 watt of interference is very difference from hundreds. Even if plane's internals are isolated, your body isn't and it may actually shorten your life, unlike some annoying yapping. Besides, people nowadays are glued to social media brainrot and not talking much.
Well i think the key thing is that aviation incidents pretty much happen once. My aerospace engineering teacher would often tell absolutely horrifying stories of catastrophes but theyd all end with "and so thats why xyz rule was implemented and there hasnt been a problem since" which is fairly comforting.
do not underestimate the battery issue! If you don't go on plane mode, your phone will try harder and harder to reach a ground antenna, draining your battery super fast
@@I_Am_Your_ProblemThe protocol of looking for signal is very energy demanding. Maintaining a signal is not. So usually you only have to use the LFS protocol maybe once or twice But in a plane, these towers would be moving so fast that the protocol would barely be finished with its handshake protocol before losing the tower, and then have to start over again. Or just not find any available towers and stay in the looking for signal protocol. Both of which are decent power drains
That's why I always turn on airplane mode while driving long distances, when you have all the maps you need downloaded, of course. Also, remember to shut its screen off if your next exit is far away, there's no reason to keep on looking at a screen that tells you no new information besides "go straight ahead" :)
Petter! What's funny is that when Veritasium asked the opening question, "How high do planes fly?" I immediately began rambling off an answer in my head, ending with, "And I know all that thanks to Mentour Pilot." And then a minute later, he appeared, as if summoned by my response.
Yeah, everyone following the Mentour Pilot channel knew that airplanes fly that high because of the air density and fuel consumption. We learned a lot from Petter over the years.
Keeping passengers belted on their seats during final approach has the added benefit of preventing somebody ooening the door when the presssure differential is almost gone
No one physically keeps anyone in their seat… everyone who has opened a door in the recent past has been able to open it whenever they want, despite the “rules” u mentioned… this is ignorant and doesn’t actually prevent anything. It’s a guide that should be followed but isn’t always followed
A question for any aeronautical engineers out there: the video asserted that planes are metal Faraday cages. Are they still? To what extent do are pressure-hulls now made of plastic composites that are transparent to radio waves? Or do they still need a sort of 'chicken-wire matrix' inside the plastic, to resist lightning strikes?
A couple things to mention: taste (particularly our sense of sweet and salty) is diminished at altitude, presumably at low ambient air pressure - which is why we think food is bland in the air. For this reason, airplane food regularly has extra salt added to it to give the food "more" flavor, to offset that effect. Try eating an airline meal when you're on the ground, it's unbearably salty. Second, I regularly use my cell phone when flying my plane - it's useful to pull up weather or other information, and for use as an emergency backup. In my experience, it works reliably up to about 3500 or 4000 feet - and then only when near a built-up area. Above 4000 feet or so, the connection is so unreliable as to be useless.
I'm a private pilot and I fly small planes, I haven't tested the limits but I've been at 10,000 feet msl, 5000 ft agl, and my phone always works fine, typically around 130-150 mph in both rural and congested areas
These people are Australians. I can't believe they don't know the rough size of their own country to realise the figures they have given are absolutely ridiculous.
@@ElVerdaderoAbejorro To be fair, they gave themselves no context. Humans are not able to conceive of large numbers. To us, it's all "many". I have experienced 30,000 from counting bacteria, but few people have direct experience of numbers anywhere near that large.
The reason FM radios operating on "adjacent frequency bands" is relevant is that they are superheterodyne receivers, and they have local oscillators that are either 10.7 MHz above or below the tuned frequency. If above the FM band, that's right on top of the aircraft navigation band... and in the past, these receivers leaked a lot more energy from the local oscillators than they do now.
@@meetmobility All superheterodyne receivers are also transmitters. In the US, FCC Part 15 applies radiated power limits to encourage proper shielding. In the UK, this is how the detection of unlicensed TV receivers worked.
That was my philosophy a few years back when the mask-wearing mandate was lifted. If most people around weren't wearing one, I'd put mine on. If they were, then I'd go without.
I agree but there is an counter argument for that as well, The more you know, The more unsafe you'll feel. It's really depends on the individual we are talking to. In a perfect word yes, That's the optimal approach to life (excluding couple of subjects that's better to not know more about if you know what I mean).
That's mot accurate. You feel less safe when you know more because you know all the tons of things that can go wrong and anyone in the chain of events that could cause your death could be an idiot and not do things right.
Great video. I've been a professional aviator for 32 years. I would just point out that until recently all commercial aircraft brought outside air into the cabin through the engines. Today, 90% of flights are like this. But the newest wide-body aircraft (like the 787) do not bring air inside through the engine (this can prevent unwanted fumes from being diverted from the engine to the passengers). Finally, these newer planes fuselages are made of carbon (not metal) and therefore are more pressurized and less dry, leading to a healthier flying experience and less fatigue!
is there a reason why it's so cold on board of intercontinental flights and quite pleasant on domestic / EU flights? I never understood why they won't turn up the temperature when people are wearing jackets onboard
@@444mm I've wondered about this too. I just always figured it was the smaller planes with people crammed in closer and not as much air circulation. But on thinking about it, that probably really shouldn't make a difference -- these planes have plenty of air circulation and have access to -50C air outside.
im a crew chief for the C-5 Galaxy, and we bring in the hot air from the engines and also cold ram air from the armpit of the wing, then the 2 different temp air mix kinda like your kitchen faucet depending on what you set the temp to.
Derek: "Today media tends to prioritize sensationalized headlines over key details." The title of this video: " What EVERYONE Gets Wrong About Planes" (capitalization mine).
“Wake up bro, Mentour Pilot and Veritasium just collabed!” 😮 You and Petter are some of the only youtubers that I genuinely get excited for with new releases. It’s rare for me to find such compelling and engaging high quality content on RUclips. I love you guys!
@@Ps5prolite In case anybody was wondering, flights per capita in 2019, the US is below the UK, Portugal and Spain. And above Italy, France, Austria and Germany. And all of those are well above places like Indonesia, Morocco, Romania, Argentina and Hungary. So in a sense, the US is pretty middle to low average across the board, even though the board is so wide. With a range from like 0.03 to above 10 flights. ~47 countries reported below a 0.1. And ~128 recorded below a 1. The US is at 2. (China at 0.46) Now, you also have this weirdly specific knowledge thanks to this bad actor or bad ai bot.
13:11 That type of interference only happened with GSM phones because they used *time division multiple access*, the beep is the radio bursting info when it’s time slot comes. Modern phones use code division multiple access and are always encoding information on the air.
I loved the old GSM phones; they were extremely useful to quickly check whether an electronic device had adequate RF shielding/immunity. I hated the manager type guy who put his phone right next to the live concert PA system.
If you're getting a beep like that when a phone is in proximity, you are not passing CE certification most likely (unless you bribe the company doing the testing)
He mentioned 800Mhz. That was the old Nextel network. It would come across on everything. The joke was that you could hear calls coming across on fire hydrants. The US moved phones off 800Mhz years ago.
What an awesome surprise to see two of my favorite RUclipsrs collaborating! Thanks Petter and Derek for years of education, entertainment and enlightenment.
13:45 It's interesting that every time there is a problem for customers, American agencies do very little... but the EU is already working to solve it. Calls on Flights, USB connections, privacy, etc.
@@Kanbei11 that was actually my guess for airplane mode being required. i just figured they didn't want to deal with the noise of people on phone calls.
That is like geostationary satellite altitude (yes, at that height, the orbital velocity matches the earth's rotational velocity, meaning that you stay over the same place).
I was a flight attendant for almost 28 years. One time, after take off, there was a hissing sound near door 4 on a 747. Turned out that the seat belt of the flight attendant seat had got stuck in the door when it was closed. The pilots depressurized the cabin (we were still climbing) and reduced speed. It took 3 guys with all our strength to lift the door lever a few centimetres so that a fourth one could haul the buckle in out of the doorframe. I was never worried anyone might open a door by accident after that. It was cool though to look for a brief moment outside through the slit that had opened and see the ground racing along 3km or so below
I was a flight attendant on a 747. I don't believe this for a second. The captain would never have allowed that, not least because he would have been fired on the spot. The door would have been armed and the slide deployed in flight. Which would have been a catastrophe in and of itself. And at 3 km high above the ground??? What BS 🤣
@@liam78587 When it comes to aircraft & safety, all airline procedures are governed by IATA and ICAO globally. I was the senior flight attendant (purser) on the 747 flying internationally. I am not skeptical of the poster's comment because it is a joke, irrational, outrageous and idiotic. If they HAD actually opened a 747 door in flight, they would never work on my crew, ever.
I feel like you always screen out the answers to questions like “how high do planes fly” so only the very worst answers are selected. You just get a lot of sensible answers compared to the few silly ones. Anyway great video, learnt a lot!

For a bunch of planespotters, their knowledge of aviation was hilariously weak.

@mirzaahmed6589 Not everyone at a viewing platform is an obsessive sometimes it's just somewhere to go to get an ice-cream on a nice day.
An aircraft mechanic here,
One of the many reasons we pump in dry air and reduce moisture content in the aircraft cabin is because water molecules present in the air will freeze into small ice blocks at high altitude which will damage a lot of the pneumatic system components including important pressure regulating valves and possibly block filters leading to blockages.
Do you even need to remove any more moisture? The outside air is extremely cold, so just warming it up should reduce the relative moisture level (relative to what moisture the air can hold at that temperature) significantly. Or is that something you only do while on the ground / close to the ground?
@@BunjiKugashira42 You're correct. They don't remove any moisture. Within the engine, as it gets compressed, the air warms up. Ice is still a concern though, but it's mainly on the leading edges of the plane. Such as the wings, because it could disrupt airflow/cause turbulence, or the first stage or two of engine blades. There it's handled by simple electric heaters.
@@zrora4385 So that explains the ice separators in the A/C ducts.?That's the rattling sound you occasionally hear above your head. But you're correct , in that at cruise altitude this is not a big problem.
What?
The engine doesn't get to choose how humid the air is it inhales. And after two stages of compression, the air is not cold anymore but actually too warm for the cabin and needs to be fed through the AC packs.
So there's no icing risk from cabin air.
@@BunjiKugashira42 Yeah, at first I thought well unless the pneumatic system gets the working fluid (the air) into the temperature even lower than before. But considering the air outside is -50 C, that doesn't sound normal.
As an aerospace engineer, I pray for the day some random person walks up to me and asks me the questions Derek asked at the beginning of the video.

You'd probably get it right and your footage wouldn't make the cut to be included in the video.
@@LuisGustavoBDthe greatest sadness when I watch these videos is I know we get such a selection bias so we have no idea how many people actually knew or not.
Your time will come, and Derek will be doing a deep-dive into the intricacies of oil painting.
“What altitude do planes fly at?”
“What direction are they heading and are they IFR or VFR?”
I always wanted to say how much I respect the decision of putting the ad last. It shows that you actually respect your audience and the respect is mutual.
Yes of course. But it's fun to hear him say "... we specifically asked ground news to sponsor this video." Meaning: Veritasium, with his 16M subscribers, gets to pick and choose who he'll allow as a sponsor, and then he'll stick them at the end of the video. Must be nice.
Pretty disingenuous to sayi it's 100% altruism...
@@RUclipsBorkedMyOldHandle_why that's sour bro

I was in a DC-8 at age eight. I discovered the little wheels in the arm rest and started to play with them. Almost immediately the cabin announcement system said "someone has moved the radar detector" and I sat stock still for the next 6 hours. It took me 30 years to reason that the radar deflection could not have been my fault
That's cute!
Nah, you know it was you that did it.

Veritasium + Mentour wasnt a collab I was expecting! Both era defining channels I would say.
For sure. Correctly said.
He got a like just for that
Same was surprised
Same. I was just thinking about how it's been a few days since I watched a Mentour Pilot video, and then boom, he's in this one. Great collab, in my opinion.
They taste like chicken
Two RUclips legends: Veritasium and Mentour Pilot.
Both in the peak of their game.
Simply awesome.
Mentour Pilot/Now is a favorite of mine. So cool to see him on the Veritasium channel.
That glazing is so pathetic.
@@maestbobo these are words of a person who neither has nor creates anything of value.
Mmmm, I wished to see 74 Gear here as well but that's a very nice collab anyway
Theyre amazing
Mentour Pilot being in a Veritasium video was a collab I didn't know I needed.
... but isn't he putting weight these days !
Time for a Veritasium deep dive into slimming products, using Petr as the guinea-pig
I remember watching some old science documentary about people living in a pressure chamber under water because the pressure was far more than one atmosphere. They complained that their carbinated drinks lost their fizz, the only flavor that didn't go bland was spicy food, and they had to be careful heating drinks because the temperature water boiled had increased.
I know it's kind of the opposite of what happens on planes, but I just find it interesting that our sense of taste is so dependent on atmospheric pressure.
Wouldn’t the drinks remain super fizzy? Part used bottles go flat because the bubbles come out until they re-pressurise the bottle itself. Just a thought
A drink will also be flat if the bubbles cant come out of the liquid due to high pressure
There is a short clip where Chris Hadfield (Canadian Astronaut) shakes a can of Coke and immediately opens it... and nothing happens because he and some others were in a high-pressure underwater structure.
@@FirestarterAJ12 The reason it tastes fizzy is because the bubbles are forced out of the liquid from the comparatively low pressure of the atmosphere than the inside of the can. If the atmosphere is closer in pressure to the can, there will be less bubbles and less fizz.
Thanks everyone. So there is a lot of fizz potential but no actual fizz!
As an aersopace engineer with more than 20 years working in aircraft development, I feel so glad to see a video like this. Factual and to the point. Great job!
My friend told me what we saw in the video, is a bit (30-40years) outdated info. Today engines operate cheaper at lower altitudes, at cruise altitude the fuel consumption is greater.
If your so smart then why haven't yall figured out the farting issue yet? Solve this issue and you'll be a retired

Your comment was full of hot air!
Oh poor soul lost any common sense when you became an aerospace engineer.
The ISS actually expands and contracts also every time it orbits due to thermocycling from exposure to the sun and space. That's one of the main reasons why space stations have a limited life.
That's very interesting
Makes sense to me, it would be a big temperature difference between SUN light and shade.
Good point. At the same time, an insulation must exist. So the question becomes is the same structure responsible for maintaining thr pressure also subject to these temperature changes
@h6ss4 oh my, a very good question indeed!
ISS circles the Earth in roughly 90minutes.
Going as high as 250 degrees F (121 C) on the sunny side and as low as -250 degrees F (-157 C) on the dark side.
So it has more circles on expand/contract that you can imagine.
I think this is the first ad/sponsor I actually went ahead and subscribed to, like ever, on RUclips.
Thank you.
PETTER! So happy to see Mentour Pilot getting some love. His channel took me from extreme flight anxiety in 2016 to a regular flier who, gasps, enjoys it! I love learning more and more about flight/planes, it has opened up the world for me.
Yeah I watch both of their videos the moment they release. This is a great collaboration. Peter has soooooo much knowledge on planes it's insane.
Me too. And the book.
Same here. 20 years without flying. I promised a friend I would go with her to Ireland. Also because Ireland is an amazing place and Irish people are incredibly nice, but first and foremost to go with my friend... So I booked a refundable ticket (yeah, not so brave...) and started watching videos about planes just to have perfect excuses to cancel the trip, because I was so afraid. I ended up on Petter's channel. No sensationalism, no overdramatisation, just a professional and detailed look on every accident, with a focus on what ended up being updated, changed, bettered... I wouldn't say I love flying (it there's a reasonably longer train ride instead, I'll gladly choose it!), but I'm way less afraid of flying now.
@@BD-nt3ee this is fantastic and I’m proud of you. It wasn’t easy, but you did it and you allowed a professional to give you real facts to start counteracting the ones our brains come up with on their own. If anyone ever asks about my journey or mentions they have similar fears, I go out of my way to recommend Mentour Pilot.

“What everyone gets wrong on planes is their drink order” - Derek while sipping on his Bloody Mary
@RUCP.RU_oN_The_Seach535don't you mean, how do you do fellow kids?
I usually order a Bloody Mary on early morning flights. Interestingly, tomato juice is mentioned in this episode about flying.
Ugh, shots of JD!
If noise would boost tomato juice consumption, it would be a very popular club drink, which it is not. I think apple and tomato juice are popular because they are not carbonated. Carbonated drinks fizz different because of the lower cabin pressure.
It sounds like something a Vampire would drink
The tomato juice connection! That's wild! I do happen to drink it on the ground as I'm a natriophile, but I do order it more often on a plane than most other beverages. Cool to know why!
7:37 "Bag of chips just popped by itself" is code for "I just farted."
😂😂
I will use this expression regularly from now on 😏
Haha, good idea 😂
I’m incredibly gassy when I fly. I fart like no other; and they’re always so forceful. It’s as if my trumpeting ass finally decides to have a personality and wants to chat.
It’s also often smelly. So on long haul flights, I’d tuck myself on all sides with the blanket. I’d often not allow my other end from talking by stretching out that starfish butt hole as much as possible as to reduce vibrations; so only forceful puffs of wind comes out. I’d then immediately dip my head into the blanket and breathe in as much of the stank as possible so others won’t be able to smell it. I’ve yet to have people complain next to me about farting in the decades I’ve been flying for my job.
7:37 is also an aircraft.
I've always absolutely loved Mentour Pilot's channel! I still remember the day I found it I binged it for many days. The amount of technical details that Petter makes easy to digest allowed me to get a little bit into aviation I never thought I would
I can relate! I was doing a lego ISS when I first came across his channel and have seen every accident breakdown since. You couldn’t have said it better. He’s the only reason I got Microsoft Flight Simulator 😅
My suggestion is to try another channel named "Green Dot Aviation"... Really good explanation on simulation basis
Similarly to some of the other comments, I studied Aeronautical engineering for four years, worked for Rolls Royce jet engines in the defence aerospace sector and been an airline pilot now for 12 years. I’ve loved Veritasium videos for years and this just proves to me how well researched these videos are. Thanks for all your effort, accuracy and clarity!

ven a 10-year-old or a 12-year-old should be able to deduce from first principles why a jet plane flies at 30,000 ft to 40,000 ft and the reason primarily they fly that high is because of less aerodynamic drag due to the lower density of air. So that you can for the same amount of thrust , you use less fuel, And still be able to maintain enough velocity to achieve lift for that altitude. ( Also, jet engines are designed to work at maximum efficiency around that altitude, Also flying above turbulence but these are secondary reasons).. Also the reason you cannot open doors is because of the pressure difference. While interior of a jetliner is pressurized to one atmospheric pressure. The pressure outside is much lower due to the altitude and air density it's flying at .A reasonably smart 10- 12-Year-Old should be able to deduce this from first principles!. Are majority of people idiots?
So why don't planes fly even higher than $30 or 40,000 feet, for even lower aerodynamic drag at the lower air density at higher altitude? Reason is yes, your aerodynamic drag will drop even further, but the velocity requirement that would be required to generate enough lift in the thin air of the higher altitude would also increase, needing greater thrust. It is sort of a u-curve. And 30 to 40,000 is usually The Sweet Spot for maximum efficient fuel efficiency. Also, there needs to be like a greater degree of pressure frame structural stresses that you need to protect against because of the greater pressure differential at the higher altitude (interior of a jet is always pressured to one atmosphere, while beyond 30 to 40,000 ft outside pressure is even lower). Also, jet engines are designed for maximum efficiency at certain altitudes windows. For these various reasons, 30 to 40 000 ft is The Sweet Spot. Anyway, I don't expect a 10 or 12-year-old to figure out the this part, but the original point I made should be evident and should be able to be deduced from first principles..
@@aryangod2003 I do agree this seems to be mostly basic knowledge that even a child would know. However I have come to the understanding of acquired knowledge supersedes the old common sense approach.
An excellent example is slippery when wet signs, or even 1st year apprentice on their first day. I feel it's better to acquire knowledge and not just believe you know it already. This in turn avoids accidents.
For instance, I knew planes go higher to save costs (along with safety of concerning lower heights plus noise).
I understood the air was 'lighter' or thinner, so obviously less resistance.
But I didn't have all the tech associated with it, or the exact reason why it's 30,000 and not 25,000. Clearly the atmosphere and even the Earth's circumference is valid.
I basically have never acquired this knowledge (no need to learn). And my common sense towards it may even be mistaken!
@@aryangod2003the major reason why commercial flights cannot go much higher than 40kft is because of air density is well, since at higher altitudes the engines will lack the oxygen (cecause of very low O2 density) so the fuel wont be able to ignite properly. Some Military airplanes’ engines are designed a bit diffrently and they can support flights up to 70-80kft
That Hawaiian flight that blew the roof off, is where Vampire Weekend got the name from their album, ‘Only God Was Above Us’ from a quote in a newspaper after that incident.
Did not know that!
That would mean that for the Chinese, God was beneath them. Good thing most are Buddhists since that religion is atheistic.
Talking about "What Everyone Gets Wrong About Planes", I'm still sometimes thinking about those poor people who clung to a departing American plane in Afghanistan
Like, incoming winds of 900km/h, -50°C, pressure so low that you can't breathe, no place to get a grip, etc
I know they most likely didn't know all that stuff but it's fascinating and terrifying how people thought they could survive it
sounds servivalble if desperate enough.
It's not even that they didn't know all stuff. It's that that was their only glimpse of hope.
@@fenilkheni9494 i don't think so
It's not that the people thought they could survive through it

Thank you for having Petter (Mentour) on your channel. He is one of the best aviation channels, if not the best, out there! Awesome collaboration, its like suddenly bumping into an old friend. Very pleasurable surprise!

“Wake up bro, it’s the collab of the month!”
Life. Get one.
Slightly unrelated... as a truck driver... I recently undid a lugnut on a trailer wheel hub, by hand...
This means, the last guy had a retorque notice that he chose to ignore (or lost and forgot)... and a tire could have come off within a trip or two (while at highway speed.)
It's a good thing the aviation industry is held to such scrutiny... much more so than the ground transportation industry. We... on the ground... have a long way to go. Truckers are always whining about 'restrictions' and 'inspections'... but how many of my 'co-workers' actually 'do their required pretips thoroughly?'
Some just sign off as good without checking anything (I've even seen trainers doing this...)
I'm assuming that's exactly how it works at Boeing as well 😂
@@Moto848 boeing kinda proves the regulation isnt enough.... no one should be dying to some company's laziness to redesign their plane for the new electric motors they want to install

Interesting what people knew about the subject, but you brought back very vivid memories when you talked about plane food. While serving overseas during the war as an aircraft technician. Civilian airlines were used for troops. On board, they were fed the same way civilian are feed. It wasn't that way for us on the ground. You can imagine what we had to eat. So when one landed, many technicians ran to prepare the plane for departure. Except we didn't go right to work doing that... we went straight for the kitchen and left over meals in the warming trays. It was just one of those things that brought a sense of home to out tummies !
Got curious today and checked when I subscribed to the channels I watch and was surprised to see Veritasium as my longest subscription. Can't believe it's been over 7yrs now and the content just keeps getting better

The plane door pressure differential reminds me of a large reach in freezer with fans that create a partial vacuum after closing. You can't open the doors no matter how hard you try.
Holy moly! I’ve watched like all Mentour Pilot’s videos, so seeing Petter on here was awesome! 2:19
As an aerospace engineer with over 20 years experience and someone who manufactures door lock actuators, the doors are actually locked on certain airplane models (i.e. Boeing 777). Flight lock actuators lock the doors of an aircraft when the weight-on-wheels signal is false (meaning the aircraft is not on-ground). This actuator moves a pin/rod into a locking meachanism effectively locking the door while in flight.
I fly the Boeing 777 and was here to add this. I'm glad I'm not the first person who noticed.
So you can't open the door if you make a belly landing, or water landing, or if the landing gear collapses. Nice.
@@niconico3907 British Airways Flight 38 would like a word with you
@@niconico3907 No, the logic for the doors is such that it would be unlocked in an emergency.
From memory, on the B787 one engine has to be running and airspeed above 80 knots for the lock to engage. Its de-energised to unlock with no electrical power.

Literally never had tomato juice beverage in my life except on long flights. I was so surprised by the amazing taste but on the ground literally never felt like even finding one to drink. When you asked that question I was like Tomato juice for me but amazingly that's the answer!!!
I've never had tomato juice on a flight, simply because it's not a drink that I normally have. However, on the next flight, there's some experimental science to be done, I can see!
Yessss! Love the collab with Mentour Pilot (my girlfriend and I absolutely binge his content)! I think every once in a while it should be highlighted just HOW incomprehensibly safe civil aviation has become, and how diligent those authorities, training infrastructures, airlines and pilots are - especially compared to the absolute insanity of car traffic that many people hardly think about.
Even a Boeing 737 MAX before the redesign of the terribly flawed MCAS was statistically safer than the average car ride.
That's always been an interesting comparison. Everyone is driving themselves, definitely don't do anything like a pre-flight, encounter obstacles constantly, and don't have autopilot (mostly). I wonder if you could control for those variables
I’m going to binge his content when I’m free at 1.25x speed
Derek and Petter are two channels I have really enjoyed independently, never would have thought of a collab but both of you are great educators and it worked really well.

200 people talking loudly on cell phones would be a disaster. Quiet is appreciated.
It's not about talking, it's about 200 watts of radio interference at sub-1 GHz long-range frequencies due to phones trying to ping cell towers at max power each.
Ironically putting a microcell on the plane might work, it can tell the phones to quiet down
@@PredatoryQQmber Don't think you watched the whole video. @dustinsullivan7216 was referencing that the EU is trying to make calls on planes a normal thing. Also they pointed out that phones don't cause interference.

You'd think Mentour's channel would make me feel more afraid of flying but i actually developed a love for aviation thanks mostly to his videos.
i like his channels because he dives deep into aviation. not just crashes and incidents but also what's going on behind the scenes.
Well i think the key thing is that aviation incidents pretty much happen once. My aerospace engineering teacher would often tell absolutely horrifying stories of catastrophes but theyd all end with "and so thats why xyz rule was implemented and there hasnt been a problem since" which is fairly comforting.
do not underestimate the battery issue! If you don't go on plane mode, your phone will try harder and harder to reach a ground antenna, draining your battery super fast
And how does it "try harder and harder"?
@@I_Am_Your_Problem progressively increasing signal strength. As you can imagine, more strength = more battery drain
@@I_Am_Your_ProblemThe protocol of looking for signal is very energy demanding. Maintaining a signal is not. So usually you only have to use the LFS protocol maybe once or twice
But in a plane, these towers would be moving so fast that the protocol would barely be finished with its handshake protocol before losing the tower, and then have to start over again. Or just not find any available towers and stay in the looking for signal protocol.
Both of which are decent power drains
This is a great explanation @@eyeswulf
That's why I always turn on airplane mode while driving long distances, when you have all the maps you need downloaded, of course. Also, remember to shut its screen off if your next exit is far away, there's no reason to keep on looking at a screen that tells you no new information besides "go straight ahead" :)
13:40 Please don't! The last thing most of us need on a flight is to spend it listening to THAT person that will talk on the phone for all of it...

Petter! What's funny is that when Veritasium asked the opening question, "How high do planes fly?" I immediately began rambling off an answer in my head, ending with, "And I know all that thanks to Mentour Pilot." And then a minute later, he appeared, as if summoned by my response.
This is exactly what happened to me
Yeah, everyone following the Mentour Pilot channel knew that airplanes fly that high because of the air density and fuel consumption. We learned a lot from Petter over the years.

A question for any aeronautical engineers out there: the video asserted that planes are metal Faraday cages. Are they still? To what extent do are pressure-hulls now made of plastic composites that are transparent to radio waves? Or do they still need a sort of 'chicken-wire matrix' inside the plastic, to resist lightning strikes?
A couple things to mention: taste (particularly our sense of sweet and salty) is diminished at altitude, presumably at low ambient air pressure - which is why we think food is bland in the air. For this reason, airplane food regularly has extra salt added to it to give the food "more" flavor, to offset that effect. Try eating an airline meal when you're on the ground, it's unbearably salty. Second, I regularly use my cell phone when flying my plane - it's useful to pull up weather or other information, and for use as an emergency backup. In my experience, it works reliably up to about 3500 or 4000 feet - and then only when near a built-up area. Above 4000 feet or so, the connection is so unreliable as to be useless.
its like a new world salt pork
Also flight speed. Anything much over 200mph and the phone will also not work.
I’ve been flying with a friend with an experimental plane, we always fly below 2,000 feet for the scenery and experience. Our phones work fine.
Food taste much better 30 metres under the sea at four atmospheres.
I'm a private pilot and I fly small planes, I haven't tested the limits but I've been at 10,000 feet msl, 5000 ft agl, and my phone always works fine, typically around 130-150 mph in both rural and congested areas

Two of my favourite channels come together! I love learning and these are the best!
The reason FM radios operating on "adjacent frequency bands" is relevant is that they are superheterodyne receivers, and they have local oscillators that are either 10.7 MHz above or below the tuned frequency. If above the FM band, that's right on top of the aircraft navigation band... and in the past, these receivers leaked a lot more energy from the local oscillators than they do now.
FM receivers are also transmitters. That's cool.
@@meetmobility All superheterodyne receivers are also transmitters. In the US, FCC Part 15 applies radiated power limits to encourage proper shielding. In the UK, this is how the detection of unlicensed TV receivers worked.

It's really depends on the individual we are talking to.
In a perfect word yes, That's the optimal approach to life (excluding couple of subjects that's better to not know more about if you know what I mean).
That's mot accurate. You feel less safe when you know more because you know all the tons of things that can go wrong and anyone in the chain of events that could cause your death could be an idiot and not do things right.
That one death. An attendant was sucked out of the plane. She was never found.
That's horrible and sad. Hopefully she blacked out and wasn't aware as she fell.
Great video. I've been a professional aviator for 32 years. I would just point out that until recently all commercial aircraft brought outside air into the cabin through the engines. Today, 90% of flights are like this. But the newest wide-body aircraft (like the 787) do not bring air inside through the engine (this can prevent unwanted fumes from being diverted from the engine to the passengers). Finally, these newer planes fuselages are made of carbon (not metal) and therefore are more pressurized and less dry, leading to a healthier flying experience and less fatigue!
The 787 uses dedicated cabin air compressors powered by electric motors.
is there a reason why it's so cold on board of intercontinental flights and quite pleasant on domestic / EU flights? I never understood why they won't turn up the temperature when people are wearing jackets onboard
@@singleproppilot Is that what they had problems with fires in the early days after rolling out the 787?
@@444mm I've wondered about this too. I just always figured it was the smaller planes with people crammed in closer and not as much air circulation. But on thinking about it, that probably really shouldn't make a difference -- these planes have plenty of air circulation and have access to -50C air outside.
im a crew chief for the C-5 Galaxy, and we bring in the hot air from the engines and also cold ram air from the armpit of the wing, then the 2 different temp air mix kinda like your kitchen faucet depending on what you set the temp to.
Loving the Mentour Pilot collab!❤
0:24 someone speaking facts.

Whoa big if true
So I'm not the only one to drink tomato juice on plane....
Learnt something new today!
Mentor Pilot is awesome. Kudos for interviewing him.
Finally, a video that debunks all those plane myths-this should be mandatory viewing for anyone who flies!
Probably best to keep it to yourself. We don't want the kook who plans to crash a plane by opening a door to come up with a new plan.
Mentour Pilot! Love the guy. I think of his videos whenever I'm on a plane 🙃
Derek: "Today media tends to prioritize sensationalized headlines over key details."
The title of this video: " What EVERYONE Gets Wrong About Planes" (capitalization mine).
As a pilot, this is the very first Veritasium video I’ve completely understood from start to finish!
“Wake up bro, Mentour Pilot and Veritasium just collabed!” 😮
You and Petter are some of the only youtubers that I genuinely get excited for with new releases. It’s rare for me to find such compelling and engaging high quality content on RUclips. I love you guys!
I was always a really nervous flyer. I've found that the disaster breakdown videos actually helped me get over a lot of that nervousness.
Not surprised. You sound like an American. Given US is like a third world compared to China, I can imagine flying is like an exotic concept to you
@@Ps5prolite what? lmao
@@Ps5prolitewhat kind of drugs are you in dude
@@Ps5prolite In case anybody was wondering, flights per capita in 2019, the US is below the UK, Portugal and Spain. And above Italy, France, Austria and Germany. And all of those are well above places like Indonesia, Morocco, Romania, Argentina and Hungary. So in a sense, the US is pretty middle to low average across the board, even though the board is so wide. With a range from like 0.03 to above 10 flights. ~47 countries reported below a 0.1. And ~128 recorded below a 1. The US is at 2. (China at 0.46)
Now, you also have this weirdly specific knowledge thanks to this bad actor or bad ai bot.
@@Piez7 Americans are peasants compared to Chinese lmao
OMG I love Mentor Pilot. His channel is binge worthy
13:11 That type of interference only happened with GSM phones because they used *time division multiple access*, the beep is the radio bursting info when it’s time slot comes. Modern phones use code division multiple access and are always encoding information on the air.
I loved the old GSM phones; they were extremely useful to quickly check whether an electronic device had adequate RF shielding/immunity.
I hated the manager type guy who put his phone right next to the live concert PA system.
If you're getting a beep like that when a phone is in proximity, you are not passing CE certification most likely (unless you bribe the company doing the testing)
He mentioned 800Mhz. That was the old Nextel network. It would come across on everything. The joke was that you could hear calls coming across on fire hydrants. The US moved phones off 800Mhz years ago.
What an awesome surprise to see two of my favorite RUclipsrs collaborating! Thanks Petter and Derek for years of education, entertainment and enlightenment.
What I've learned: If you want to escape an airplane, wait till someone flushes the toilet.
That's actually smart. For better chances, get a bunch of friends that flush all toilets at the same time 👍
😂
Don't drop a b**b in there 😂
If you want to taste the food during flight, use a mistefire fan to moisten the air around you. It really works 😉👍
8:25 the one person who died was a flight attendant, who wasn't strapped to her seat.
It was just too hard to wait on the passengers while carrying that heavy seat around.
13:45 It's interesting that every time there is a problem for customers, American agencies do very little... but the EU is already working to solve it. Calls on Flights, USB connections, privacy, etc.
Eu is the best place to live
Common EU W. Plain and simple: the EU cares about its citizens, the US cares about its businesses
I'm not sure if calls on planes is a good thing though. We could do without it in my opinion solely from a noise perspective
@@Kanbei11 that was actually my guess for airplane mode being required. i just figured they didn't want to deal with the noise of people on phone calls.
I think that is because EU spends less time on taking over the world, Pinky. 😊
Really??? 25.000 km? 😂
Great to see Petter on you channel! 👌
That is like geostationary satellite altitude (yes, at that height, the orbital velocity matches the earth's rotational velocity, meaning that you stay over the same place).
as an aviation enthusiast and future flight attendant, that hurt so much to hear
My guess is those people were confusing kilometers with meters.
We aren't experts and knowledgeable about everything.
😂😂
I was so excited to see Petter from Mentour Pilot make an appearance in this video. One of my all time favorite channels!
Two of my favorite youtubers in one video! I love it!
I was a flight attendant for almost 28 years. One time, after take off, there was a hissing sound near door 4 on a 747. Turned out that the seat belt of the flight attendant seat had got stuck in the door when it was closed. The pilots depressurized the cabin (we were still climbing) and reduced speed. It took 3 guys with all our strength to lift the door lever a few centimetres so that a fourth one could haul the buckle in out of the doorframe. I was never worried anyone might open a door by accident after that. It was cool though to look for a brief moment outside through the slit that had opened and see the ground racing along 3km or so below
I was a flight attendant on a 747. I don't believe this for a second. The captain would never have allowed that, not least because he would have been fired on the spot. The door would have been armed and the slide deployed in flight. Which would have been a catastrophe in and of itself. And at 3 km high above the ground??? What BS 🤣
@@m.duplessis2154 same im calling bs thats fuvking dangerous af and no captain in their right mind would allow that
@@m.duplessis2154 That person said it, so it is true. That is how true works.
@@m.duplessis2154 not all airlines are the same different countries different rules
do i believe it? i mean it's not worth being skeptical about
@@liam78587 When it comes to aircraft & safety, all airline procedures are governed by IATA and ICAO globally. I was the senior flight attendant (purser) on the 747 flying internationally. I am not skeptical of the poster's comment because it is a joke, irrational, outrageous and idiotic. If they HAD actually opened a 747 door in flight, they would never work on my crew, ever.
I will be interviewed by a huge airline company in a few days as a cadet pilot and this video boosted my morale upwards. Great timing!

I feel like you always screen out the answers to questions like “how high do planes fly” so only the very worst answers are selected. You just get a lot of sensible answers compared to the few silly ones. Anyway great video, learnt a lot!
5:28 so your telling me if I flush the toilet enough times I can make the air un breathable
😂
Well, if you need to flush the toilet THAT many times in the first place, the air in the plane will be unbreathable already
@@Georgian_guy-1 😂😂
But the engines regularly repressurize the plane, which will casually undo your efforts.
