Winged objects are supposed to be symetrical for some reason. Left wing and Right wing. Wings are not quite a true ying & yang thing .... otherwise there would be something more like wing and anti-wing .... probably what they have in things like parachutes. Airplanes and ducks are supposed to have both wings attached to the fuselage.
This video demonstrates one advantage of horsepower as compared to duck power. While it is not quite possible for the airplane to suspend itself in the air by its propeller, it can certainly slow itself down a lot.
Mostly what happens is this ..... if God thinks you are supposed to wash dishes tomorrow, you're gonna make it through today!
