Eric Stanley Lock, DSO, DFC & Bar (19 April 1919 – 3 August 1941) was a British Royal Air Force (RAF) fighter pilot and flying ace of the Second World War. Born in Shrewsbury in 1919, Lock had his first experience of flying as a teenager. In the late 1930s with war a possibility and the likely event of him being called to arms, Lock decided that he would prefer to fight as an airman. He joined the RAF in 1939. He completed his training in 1940 and was posted to No. 41 Squadron RAF in time for the Battle of Britain. Lock became the RAF's most successful Allied pilot during the battle, shooting down 21 German aircraft and sharing in the destruction of one.
