Let me tell you something that you may not know. Do you know how the plane slows down? Is it by the pilot&;s foot to brake? In fact, after the plane lands, the pilot will pull up the reverse thrust. Careful friends will definitely find that the engine of the plane will open a hole soon after landing and touching the ground. This hole is the mouth of the aircraft engine&;s reverse thrust. Originally, the engine was backward. When pushing back, it will jet forward through this hole to help slow down.
