the wheels are just letting the plane sit there because there the only things moving in the wheels were locked up the plane will move backwards but since there free to spin there just letting the plane sit there... put rollerblades on a tredmill and turn it on whats going to happen if you do what the plane does... therotically speaking if you push foward on the rollerblade then the speed of the tredmill increases so your right back to where you started from
