Flight

[Freak]

A plane is standing on a runway that is made of a large conveyor belt.
The plane fires up its engines, but as it moves forward, the conveyor belt senses the speed of the plane's wheels and moves at exactly the same speed in the opposite direction.

Can the plane take off?

Yes because the plane has thrust and the way a planes wing works is air flows over the curve of the wing, causing low pressure on top and high pressure on the bottom of the wing, therefore causing lift, and causing the plane to rise into the air, and start moving in a lateral direction, which we would call flight.

-Edit-
To understand better, high pressure ALWAYS moves to low pressure.

Think of it this way. Two people are pushing on a door |.

One is pushing on this way ---> | and the other pushing on this side | <---.

If both push at the same pressure, the door wouldn't move. ---> | <---

But if the person on the left side, doesn't put as much force on to the door, -> | <---, then the opposite side will have a greater force. The greater force will "move" to the lower force, to equalize, and the door will swing open.

Same with a planes wing. High pressure forms below the wing, low pressure on top. The high pressure "pushes" upward harder than the low pressure can push downward, and the plane lifts into the air.
