Depends on what you compare it to. An airplane has to move in relation to the air to stay flying, but it doesn't really care about what the ground is doing. If it's windy enough you can point a slow-flying airplane into the wind and remain flying while not moving in relation to the ground.
Due to "turbulence" - that is movement of the air though which the plane is passing.
I think it can

I am going to assume that aeroplane=airplane when I answer this. An airplane stays in the air by generating lift on its wings. As long as an airplane can generate sufficent lift it can stay in the air. However once the lift being generated falls below what is required for the plane to stay up... uh oh.
You can, if in reasonable distance, with the right weather conditions.
A rocket goes into space and an aeroplane stays on Earth and flies in the sky.
planets stay in the sky due to the pull of gravity
Many military jets can fly up to or over 50,000 feet.
