of birds, but has been extended to include the wings of insects
(see insect wing), bats, pterosaurs, and aircraft.

wing's aerodynamic quality is expressed as a Lift-to-drag ratio.
The lift generated by a wing at a given speed and angle of attack
can be 1-2 orders of magnitude greater than the drag. This means
that a significantly smaller thrust force can be applied to
propel the wing through the air in order to obtain a specified
