Why do airplanes fly so high?

Better speed and fuel economy are the main reasons, but there are also other advantages: 1. You avoid most bad weather at 30 - 40,000 feet 2. No mountains to watch out for 3.

The higher you are, the longer you can glide incase something serious happens to the plane (ex: both engines fail). 4. You can avoid low flying aircraft and birds.

Even though humans will not build buildings 10,000 feet tall there are still mountains taller than 10,000. Mt. Everest is just over 29,000 tall.

It would ruin your whole day if you fly into granite cumulus. Joking aside, the higher you fly the less fuel you use and you go faster because the higher you are there is less air to impede you forward progress. You also avoid most of the bad weather and all the bad things that go with it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
