The design was marked P.59, and its concepts were refined in 1939 in the P.59-05 variant, after which the design was put in a drawer. This type of plane was not needed at the time. Nevertheless, limited experimental work was carried out, the result of which was a small Goppingen Go-9 plane, with an aerodynamic system obtained from P.59, as well as three-support landing gear with a front wheel and an engine driving a push propeller through a long shaft.     The results of these experiments were used when designing the P.231 aircraft in several variants - also combining piston and jet propulsion. When in 1942 the RLM announced the requirements for a high-speed multipurpose aircraft, the equivalent of the British Mosquito, Dornier proposed the P.231 as a rather unusual answer. Despite the risks posed by the different P.231 concept, Dornier was commissioned to build several prototypes.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49743611494673,"sku":"NGR9788366673786","price":23.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/8366673782.jpg?v=1750775637","url":"https:\/\/www.worldofbooks.com\/products\/dornier-do-335-pfeil-a-book-marek-ry-9788366673786","provider":"World of Books ","version":"1.0","type":"link"}
