At high altitudes the atmosphere is less dense that at lower altitudes. This means that planes flying higher experience less drag (friction) than those lower down, so that means they can go faster.
Small planes fly at 100 to 200 mph. Airliners fly around 350 to 500 mph. Jet fighters fly faster.
They have to stay away from other planes so flying at different heights gives them room. Several can be "stacked".
Bombers 30,000 ft Fighters 40,000 ft
The heights model aircraft fly is really only governed by how far their controllers can see. In theory they can fly thousand of meters high.
Planes are not perfect but they are not the worst to fly in because it can be safe but it cant be sometimes most of the time it is great to fly in so most of the time planes are safe.
Fly is so cool they fly from flight At great height there is little atmospheric disturbance, so planes do not get buffeted and the flight is smoother.
Every airplane has its own speed limits. Most small and commercial planes fly below Mach (the speed of sound). Military fighters and some other planes, like Concorde, fly above Mach, or supersonically.
It has a very good eye sight.It can fly at great heights.
Of course, planes can fly.
There are MANY different fighter planes so a definitive answer is impossible. Most modern fighters fly between 1,200 and 1,600 mph.
The Great Plains are the stretch of land that runs through the Midwest of the United States. Make sure you spell it plains not planes because planes are the things that fly through the air!
Fighter planes are designed specifically to shoot down other planes. It was in response to bombers and reconnaissance aircraft that they wanted to prevent from flying over the ground forces. Then there had to be aircraft to fly with the bombers to prevent the enemies fighters from shooting them down.
