The P.W.S.8 was a 1930 Polish sports plane, constructed by the Podlaska Wytwórnia Samolotów (PWS), that remained a prototype.
==Design and development== The plane was designed in 1929 by Jarosław Naleszkiewicz in Podlaska Wytwórnia Samolotów, on factory's initiative, to participate in the Challenge 1930 international touring aircraft contest (with P.W.S.50, P.W.S.51 and P.W.S.52). It was a wooden biplane, partly modelled after de Havilland Gipsy Moth. Its unique feature, taken from earlier PWS military aircraft, like P.W.S.5, were N-shaped struts between lower and upper wing and additional oblique transverse struts, stiffening the design, instead of wire braces (similar bracing to Handley Page Gugnunc).
