Why do planes need to fly so high?
First, the word is aerodynamic. Second, air resistance is *higher* at lower altitudes because air is denser there. There is less drag higher up.
The Short Answer
First, the word is aerodynamic. Second, air resistance is *higher* at lower altitudes because air is denser there. There is less drag higher up. Flying lower is not safer. At a high altitude, a plane that develops a problem has time to fix the problem or go to a different airport. A plane at a low altitude has to land where it is, which may be very bad.
