Aerodynamic Smart Bird Airline. These provide us with fascinating and illuminating examples of unsteady aerodynamics. Both a passenger jet and a tiny paper airplane are governed by the same forces.

Independent wing control has the potential to provide a greater flight envelope. Force traces (n = 5 birds, n = 4 flights per bird) show the contributions of lift and drag to the net vertical (e). Everything moving through the air (including airplanes, rockets, and birds) is affected by aerodynamics.
