[QUOTE=GP99GT]For a more down to earth example...
Take a toy car, no motors, 4 wheels that just roll. hold it on a moving treadmill with your hand - speeds are matched at that point. No matter how fast that treadmill is moving, it still takes the same amount of power from your hand to move that car forward on the treadmill - apply that concept to the plane.QUOTE]
but its different the plane has a motor to push it under its own power
