What Everyone Gets Wrong About Planes

most plane doors aren't locked there are no keys No sensors or passcodes to secure them if someone wants to pull the lever they can a man opened the emergency exit door and forced his way off the plane and yet with 40 million flights each year these doors are virtually never opened in flight so why not your self-preservation surely Common Sense most people are you know smart enough to not mess with that the real answer relies on where planes fly how high do planes fly approximately 10,000 km or is that overshooting it I think that's overshooting it I think you'd be in space 25,000 km that's the height of a plane flying is that way too low it's too much it's it's too much too much too much bring it in maybe 1,000 km 1,000 km still space 50,000 fet I think some of them can go up to 43,000 Ft 30,000 ft 38,000 ft yeah yeah why do they fly that high uh I don't know safety I guess probably to avoid um collision with other aircrafts and if there's high mountain ranges I don't know when the When Storms or or or weather hit my guess is to avoid a turbulent weather I think that's a decent guess now it's true that one of the benefits of flying at 30,000 ft is a smoother ride this is high in the troposphere the layer in which most weather occurs so there's less turbulence and fewer storms to navigate around but this is not the main reason that planes fly so high the bigger reason of course is money as you go up the density of air decreases and at 33,000 ft or 10 km the density of air is just a third of what it is at sea level so flying at this altitude the plane runs into a third of the air molecules it would closer to the ground that means the plane can fly about 73% faster for the same amount of thrust and as a result you get to your destination faster and since you spend less time in the air you burn less fuel it seems in a way that like climbing is wasted energy can you compare like The Descent to the ascent do you essentially get the energy back as you fall down the other side yeah when we ...
