Vaughn Jr., 17th Aero Squadron]] A '''biplane''' is a [[fixed-wing aircraft]] that has two fixed wings.<ref>{{Cite book|url=https://books.google.com/books?id=AEUEAAAAMAAJ&q=biplane+description|title=Monoplanes and Biplanes, Their Design, Construction and Operation|last=Loening|first=Grover|date=1911|publisher=Munn, Incorporated|language=en}}</ref> The lower wing is often attached to the body of the [[aircraft]] and the top wing is raised above. Most early airplanes were biplanes because they have a stronger structure than a [[monoplane]]. When [[engineer]]<nowiki/>s discovered how to make strong monoplanes, biplanes became rare because they produce more [[Drag (physics)|drag]]. Famous biplanes include the [[Polikarpov Po-2]], [[Sopwith Camel]], [[Avro Tutor]], [[Antonov An-2]], [[Beechcraft Staggerwing]], [[Boeing Stearman]], [[Bristol Bulldog]], [[Curtiss JN-4]], [[de Havilland Tiger Moth]], [[Fairey Swordfish]], [[Hawker Hart]], [[Pitts Special]] and the [[Wright Flyer]]. The Stearman is particularly associated with stunt flying with wing-walkers. ==References== {{reflist}} {{aircraft}} {{transport-stub}} [[Category:Aircraft]]
