I hope I convey my point probably, but why do planes go so many thousands of feet in the air? Is it faster that way, or could they achieve similar flight times at a lower altitude?
Does it have something to do with the curvature of the earth?
In: Engineering
The higher up you go, the thinner the air is. That means it’s easier for a plane to push through the air, so it goes faster with less fuel.
Also, if you’re lower, the sound from the jet engines are going to be a lot more disruptive on the ground.
