The Westland Lysander was a British army co-operation and liaison aircraft produced by Westland Aircraft used immediately before and during the Second World War. After becoming obsolete in the army co-operation role, the aircraft's exceptional short-field performance enabled clandestine missions using small, unprepared airstrips behind enemy lines to place or recover agents, particularly in occupied France with the French Resistance help. Like other British army air co-operation aircraft it was given the name of a mythical or legendary leader, in this case the Spartan general Lysander.
