LUCKILY this conveyer has a system which tunes its speed to the plane, so it is always moving at the same speed as the plane. how can something proceed to move forward it the ground below it is moving in the opposite direction?
You are thinking of a car. A car would be diffrent because it uses it's wheels to move forward. A plane doesn't.

This significantly diminishes the pressure of air on the wing; the difference of pressure under and over the wings creates the necessary lift for flight.
on a belt that would not happen because the plane it not actually moving it staying still... the only movement are the wheels.

Now if your homo friend turns on the treadmill, the plane will fall off the back. Seems normal enough right?
Ok, now hold onto the plane with your hand. Have your friend turn on the treadmill on low. Can you still move the plane forward on the treadmill? Sure you can! The wheels will be spinning faster, but since the plane is not getting it's force from the wheels, it's getting it's forward moving force from you, it will still be able to move forward no matter what the wheels are doing.
Go ahead and have some fun and turn the treadmill on high/full speed. Can you still move the toy plane forward? OF COURSE YOU CAN. It's very simple. The toy plane and the real plane don't use the wheels for forward movement. They get their thrust from you or the planes engines. Sure the wheels will be spinning really fast, but that won't stop the plane from moving foward.

A plane is standing on runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in opposite direction).
The question is:
Will the plane take off or not? Will it be able to run up and take off?"

but then the wheels would have to move faster then the belt which is not possible because "This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same"
