This makes me wonder if we'll start seeing wings which change in shape depending on the stage of flight. It is my understanding that the up-turned wing tips reduce ground-effect lift, which creates an upward force on the wing as the plane comes in to land. If the wing tip is not beneficial in flight, maybe we'll start seeing the extra surface area used for lift during flight, and turned up only during landing and taxiing.
