OK, If I'm running on a treadmill, and the treadmill is matching the speed at which I'm running then I don't move.

Now, lets say that I decide while I'm running, that I want to "walk" down the handrails using my arms. Does it matter how fast the treadmill and my feet are moving? NO.

The plane is not moving because of it's wheels, it's moving because of the engines acting against the air.
