Leutnant Heinz Schnabel and Oberleutnant Harry Wappler were two German prisoners of war (PoW) who made a daring, but unsuccessful attempt, to fly from captivity in England to the Netherlands during the Second World War. They managed to hijack a training aircraft and then attempt to fly to the continent, only to turn back due to lack of fuel. They were subsequently caught and later transferred to Canada for the rest of the war.
