Low aspect ratio wings like on a fighter airplane have much more of this type of drag. The shape of a wing greatly influences the performance of an airplane. The speed of an airplane, its maneuverability, its handling qualities, all are very dependent on the shape of the wings. The straight wing is found mostly on small, low-speed airplanes. General Aviation airplanes often have straight wings.
Sailplanes also use a straight wing design.
These wings give the most efficient lift at low speeds, but are not very good for high speed flight approaching the speed of sound. The swept wing design creates less drag, but is somewhat more unstable for flight at low speeds. A high sweep wing delays the formation of shock waves on the airplane as it nears the speed of sound. How much sweep a wing design is given depends upon the purpose for which the airplane is designed to be used. A commercial jetliner has a moderate sweep.
