Ok so what were saying is that the treadmill is going FORWARD and Im going FORWARD both of us at the same speed yes this will double my speed. but if im going------> that way and the treadmill is going <------ that way the 2 speeds will cancel each other out . now if what ruiner is talking about the treadmill and the plane both going the same way then yes I can understand the plane taking of but if they are going in different directions the no the plane will not fly.
