seems like the wrong way to go to me. if you want a swimmer to go fast, you create a sharkskin textured suit and she swims faster (until, of course, they ban the suit from competitive events). i would think that if the goal was to fly with less resisitance, the natural response would be to dimple the surface of the airplane just like a golf ball. actually, the really natural thing to do would be to cover the entire plane in feathers!
