This isn't a particularly new or novel question but for those of you who maybe haven't seen it before this is always a fun topic of conversation! The question is: "A plane is standing on a runway that can move (some sort of conveyer belt). The plane moves in one direction, while the conveyer belt moves in the opposite direction. This conveyer belt has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same but in the opposite direction as the plane. Can the plane take off?"
