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
if you go higher up, you find thinner air, and thinner air causes less drag, and less drag means you can go faster and less power is needed and so it uses less fuel and it’s cheaper
also it’s higher than most weather, so you are gonna have less turbulence, and you can have Jetstreams which are consistent winds that help the aircraft go faster by getting tailwind
