If a plane is on a conveyor belt that is moving against the plane, can it take off? Let's see what Gary's Mod and the Source engine say. Note that the purpose of this video is not to show that the plane can take off (the Source engine limits me from testing this), but that the conveyor belt has no effect on the speed of the plane.
