I should also remark the laminar fluid boundary layer only is true for subsonic flight. When you go over Mach one, a permanent shock wave forms in front of the wing. This shock wave disrupts the laminar boundary layer. Lift is achieved by Newtonian breakdown of the air hitting the wings underside. This is why supersonic planes require fly by wire. As computers are constantly issuing commands to ailerons and rudder to prevent stall.
