And having Peter from Mentor pilot on is a bonus! I watch all of his videos and yours too! Thanks!>> <<@georgemetaxas9227 says : Climate change puts more heat in the oceans, and that will produce more unstable and violent weather, that is not a good thing for aviation anyway. Curiously, high flying planes producing contrails may help the atmosphere cool a little bit, a benefit that may be partially lost if sustainable fuels that burn more clean, would be used in the future. I think Mentour has a video about that.>> <<@paradiseisland69 says : What about fume events?>> <<@Darkmule01 says : I have no skills. I have no education in planes. My common sense told me exactly what he described almost word for word. I need something more to think about. I think I'm getting bored too quickly. Good vid, ty.>> <<@boyeatsworld-vr9ci says : lol! Do you think climate change affects turbulance? LMAO! we will never know since climate change is a hoax>> <<@boyeatsworld-vr9ci says : airplane mode does nothing to protect a flight.>> <<@Technichian462 says : The reason air travel seems to be more turbulent lately is because of a change to save some fuel. The glide slope has been increased, dramatically. Instead of staying at altitude for most of the trip, the glide slop will start as soon as possible. Gliding as much as possible, putting the aircraft in much more turbulent air.>> <<@danielpetzen says : Thanks for yet another super interesting video! Having worked with developing mobile phone base stations, I've always been at a complete loss as to how these ideas about mobile devices being a threat to airplane safety came about, as it made absolutely no sense to me. I've admittedly not looked that hard, but none of these restrictions were ever backed up with any facts. It's a bit scary that the reason for this is that there have been no proper research - at all. Let's just hope that we don't get a new Covid-19 outbreak if 5G is allowed on planes 😁>> <<@Cthooligan says : I'm getting a sinus headache just watching this>> <<@svendtveskg5719 says : Well, I still don´t feel I get the decent amount of credit for being the guy, that has held numerous planes up in the air by lifting them in my armrests.>> <<@TimpBizkit says : Being that a plane falls out of the sky if you fly too slowly, does flying higher just make the plane faster until it reaches the same drag as lower down. So at sea level you might only reach 250 mph, but at 30,000 feet you reach 650 mph but the drag is the same? I suppose though even if that were the case, a thrust engine is better impedance matched at higher speed. Blasting out hot gas at 700 mph to make a plane go 30 mph is inefficient. The physical (not thermal) power of the engine is thrust x thrust velocity. A human powered helicopter and a jetpack make about the same thrust - your bodyweight + equipment weight. The gas coming out the jetpack is much faster and a jetpack is very fuel thirsty compared to the human powered helicopter that slowly rotates 4 giant rotors powered by your legs. The air velocity is very low so it's really easy to create that much force over a wide area. You transfer more power from your engine when you are a bit below the exhaust gas speed.>> <<@tonyclifton265 says : now i dont feel like such a shitheel for farting continuously on long haul flights - it's the air pressure's fault. apparently when planes land and the ground staff open the door they stand well back cos the air stinks so bad. stale and farty. you just dont notice it as a passenger but it's nasty AF>> <<@sugarpolecat4781 says : I remember there was this plane racing game, where you flew faster closer to the ground, and I was like - "this is stupid". But it worked for the game, since there are more dangers near the ground, so it was a risk/reward kind of thing, but already as a kid I knew this is not how that works (I mean we did have physics in elementary school so). Anyway, fantastic video! there is some stuff that I didn't know about planes so it's always amazing to learn something!>> <<@Bertg1982 says : Mentor pilot!! 😂>> <<@AlexDogwalker1234 says : MENTOR PILOT <3 <3 <3 <3 And i love airplane food. Can perceive zero difference.>> <<@theonetheycallfear8237 says : Right at the commercial break of “it’s all about money” I get an ad for Den of Thieves 2 where the first line is “it’s not about the money” 😂>> <<@RVWeekendsRC1 says : I’m getting tomato juice on my next flight:)>> <<@lord_flashheart says : Basically grade 5 physics>> <<@MJG822 says : That looks an awful lot like Wings Over Illawarra Airshow at Wollongong Airport>> <<@frankb1 says : The change in air pressure causes you fart more. The lower relative humidity reduces your sense of smell. That works.>> <<@atoms-to-atoms says : 30 000>> <<@bobsimmons1470 says : I'm team fart on a plane and before anybody answered I already knew the answer. I never thought I would feel smart by saying this.>> <<@ruidias6333 says : They are called "airplanes" or "aeroplanes" if you prefer the old spelling. Ironic when a post about what everyone gets wrong about a subjects....gets the name of the subject wrong!>> <<@vanevans645 says : The reason Europe can allow cell phone usage in flights is because European phones operate on a different range in the band, a little lower than US cell phones. The upper band of US phones borders the band of avionics, mostly the altimeter, which could cause problems. There is enough wiggle room for European phone, but not US phones.>> <<@jim-r7b1f says : Also worth noting all plane doors on every side front and back open into the oncoming wind. Don't know if that was intentionally designed>> <<@Plankmeister says : Experienced skydiver here... Farting at altitude (4km) in an unpressurized cabin is *definitely* more common than at lower altitudes. Sometimes it really does feel like it's being sucked out of you.>> <<@Ed19601 says : abt 9-10 km>> <<@georgenicholai6089 says : I fly Alaska Air and their food is excellent.>> <<@SmartMoneyRyan says : at 3:39 air pressure doesnt fall off faster at altitude than density because of the air above you, its because air is compressible, temperature and the effects of gravity being stronger closer to the surface of the earth.. air pushes on all sides equally becaues it's free to flow, so it doesnt matter how much there is above you, in that sense, it really matters how much is around you, how much gravity is acting on it and it's temperature. the lines not matching up in your video i would assume is mostly from temperature. but may be some of the other factors aswell. temperature on a gas doesnt change linearly with pressure and density. look at "Ideal Gas Law" the relationship to temperature - pressure and density.>> <<@neon1899 says : "Do you fart more in the airplane?" "100%" Girl at 7:20 : WTF DAD!>> <<@saM_humor says : Veritasium do vid on MSG>> <<@helendunn9905 says : Two great YouTubers collaborating, yay! 😂❤ Is this inevitable? 😮❤>> <<@shawnheneghan4110 says : Tomato Juice is generally very high in salt.>> <<@idahogie says : As someone who enjoys toying with flat Earthers ... I feel like the main misconception regarding plane flight is that they have to "turn down" in order to remain close to the Earth's surface. Yes, flat Earthers think that a plane will fly off into space unless the pilots "turn down.">> <<@steveking7719 says : that was a loaded question... you're assuming climate change is real.>> <<@peakinterview4205 says : I had to laugh. For many years I flew internationally for business. I always drank tomato juice. Now, many years later, I flew back from Florida a couple of weeks ago, and guess what my inflight drink was...Tomato Juice! I don't drink it on the ground.>> <<@EdwinLLT11 says : Hey man I know you have to do your grind, but completely changing the title and thumbnail of old videos not only tricks your own subscribers but it also caters to people who wouldn't genuinely watch your content.>> <<@Threeheadedbeastmode says : Mr. And ms. T is my number one choice.>> <<@user-nd7sc8wq4c says : Ah yes, a video about airplanes being sponsored by ground news, how poetic.>> <<@mjallen1308 says : Tomato juice? No. No thank you Derek.>> <<@stevedavenport1202 says : Mentour Pilot in da house 😀👍>> <<@angeloperezceo8101 says : I'll try tomato juice on a flight>> <<@davidmontville4885 says : 10:07 sitting on apron, not tarmac>> <<@paulcostache6733 says : How bad did Boeing mess up to lose an airplane door then….>> <<@АналитикДиванный-ъ7ь says : I always eat out with appetite that plane food. For me it as tasty as I was eating out on a picnic in the wild>> <<@virginieslagmolen7147 says : I learn a lot from this video only missing the radiation in airplane...>> <<@adamreynolds3863 says : what is the altitude of cloud seeding?>>
