Have you ever been on a people mover (one of those flat escalators like at the airport)? Lets say you are walking againts it and you are holding a cannon. Fire the cannon behind you and I guarantee it'll knock you on your face.

The engines that suck air from in front of the plane and push it behind the plane don't really give a crap about its wheel speed.
