Good luck getting to that door. Plus, I’m almost certain there is. Or some kind of safety release. Idk I don’t want to test that.>> <<@SuscribetoRandomer says : People should watch this, especially my brainrotted classmates 😭✌️>> <<@Tumblecrumb says : The pressure in the cabin is strong the second the wheels come off the ground… you ain’t opening any door.. good luck.>> <<@TandTsoccer says : how efficient is engine trust in 1/3 of atmosphere.>> <<@V0ID_beats says : 10.000 km? How are these people alive?>> <<@Twenty2246 says : Watching this while on an 11hr flight. Btw the plane is an A330-900NEO, cruising altitude has gone between 35-40k feet.>> <<@johnstreet797 says : No phone on the plane, I'm not that important, and neither are you.>> <<@lalwanivishal89 says : two of my favourite channels working together :D>> <<@jamestrank5928 says : Tomato juice on plane thing is not really because you're craving it, simply because they offer it.>> <<@BooTub3 says : Why did they all go from metric c>> <<@ColdDev-f3u says : What’s up with the bee movie? Bees on steroids ahh>> <<@Tornado_chaser58 says : Why there never opened in flight: who is stupid enough to do that? Why there never locked: what if they forget a passenger that was sleeping inside (yes, this happened before)>> <<@Pakistan.zindabad87 says : Seeing this while boarding a plane 😂>> <<@tswag1842 says : drag, its always drag>> <<@reneskrt says : I don’t see why they don’t let us bring parachutes on a plane worst case scenario you jump out with it….>> <<@yose-n6u6d says : Food on turkish airlines taste better than any western food on the ground... so it's not about the plane or air.>> <<@joshuabeaver8022 says : The international space station is pressurised to sea level pressure because the ISS is in a pool on earth. That is also why it is only pressurised once>> <<@djxgam1ng says : Is that why they serve peanuts on flights?>> <<@Philippinzo says : 67>> <<@RobDaRub says : i feel so smart knowing all of this without the video>> <<@nickymaurice1507 says : @4:33 the down side... people need air lol>> <<@JamesCollins-w7r says : Some mountaineers have climbed Mount Everest without oxygen canisters.>> <<@陈强-m9s says : 2:36 787: Hold my bleedless GEnx (or Trent 1000) Instead bleed air from the engine compressor stages for cabin air and anti-icing, 787 relies on electric cabin air compressors...>> <<@aterxter3437 says : 5G radio towers ... interfering with altimetric radar They only go horizontally... and what about diffraction?>> <<@aterxter3437 says : Aerospace engineering student here : No a jet engine isn't more efficient with increased altitude. A turbojet and a turbofan 's efficiency DECREASES with altitude (the thermodynamic cycle is less efficient). BUT a jet engine is optimised for a range of airspeeds and altitudes around a given operating point, and that is the cruising altitude as the plane spends most time there, so yes, it is less efficient at sea levelm but it's not a fact about pure efficiency, but the efficiency of the individual parts that are designed for one set of operating conditions>> <<@johnblair8760 says : I'd ace the first question thanks to nickleback "I wanna join the mile high club at 37 thousand feet">> <<@pongbravo5822 says : thanks>> <<@yidiwang7264 says : my kid really likes the background music starting from 7:55! What music is it?>> <<@HiddenSystems90 says : kudos to you guys>> <<@Lar5u5 says : Some aircraft doors actually do have locks. 777 and 787's have flight locks on their doors. 737 overwing doors also lock. All these doors lock and unlock automatically.>> <<@mayuriot says : Everytime a sat on an airplane my ear sound pop! Pop! And lot of pain>> <<@murisija says : Private equity has found doubleganger and paired their channels and some lowly paid intern is writing the scripts>> <<@BadDreamFker says : Clarabelle "C.B." Lansing was the lone fatality on the Aloha Airlines flight 243 accident. She was sucked out of the cabin and never found.>> <<@romanburtoviy8224 says : How do I block a channel this guy keeps popping up everywhere its really annoying>> <<@vkfunact5022 says : So at that height how does the lift happens when there is less air molecules.>> <<@yourstruely43216 says : So how at 911 they could call outside...>> <<@Coolface-f8r says : 18:49 It is not possible to get to this time. You have *actually* reached the end of timed comments>> <<@shayYaMaat says : This whole video could have been an email>> <<@Andy_Hikes says : Only one person died? That’s pretty catastrophic>> <<@saardean4481 says : Can somebody educate me? If there is 1/3 of the air molecules at high altitude, doesn’t also Lift get less?>> <<@asleepawake3645 says : Ooh a collab of my favorote channels>> <<@eklhaft4531 says : My favourite colab ❤>> <<@paolovidal3307 says : bag of chips was shakespearean levels of wit>> <<@ThatTrainGuyxD says : 13:49 what you forgot to think about is that smartphones in the US communicate really close to the frequency planes use to communicate, but in the EU network, there is a lot bigger of a gap, so there is nearly no interference>> <<@AstroGaminggggg says : 17:30 I KNEW IT>> <<@DR.Alaska says : Air is weather goofy>> <<@nosafetyswitch9378 says : Ever since I moved to London, everything I go back home I like to bring a couple bottles of Greek virgin olive oil with me. The bottles were used cola 1.5l bottles. The first time I did it, some of it spilled out of the bottle and messed up my bag. I then sat down and thought about it a bit, having oreviously observed that crisps were inflated during flight and then squeezed back to shape when landing. Next time, I squeezed all the air out of the bottles so that they only contained olive oil and maybe a mm or 2 of air, then sealed them a bit with duct tape. Never had any spill since. Physics can be fun but also USEFUL.>> <<@DMWANO says : How anyone thinks a plane flies at 25,000km is beyond me 😅>>
