The Westland Lysander is a British military cooperation and liaison aircraft, with a metal structure in the high wing structure with a classic tail from the Second World War. Design works, under the supervision of William Peter, started in 1934, two years later a prototype was flown, and already in 1937 serial production started. The Lysander was produced between 1937 and 1942 in five main versions: Mk.I, Mk.II, Mk.III, Mk.IIIA and TT Mk.IIIA. All versions were powered by Bristol Mercury or Bristol Perseus engines. A total of 1,425 machines of all versions were built. During the French campaign in 1940, they served on the front lines, but suffered considerable losses there, which led to their shifting to other tasks: saving the crews of downed bombers, maintaining communication with the underground in occupied Europe, reconnaissance. This type of aircraft was also used by the Polish 309th Division of cooperation with the Army.
