Flying Officer Derek Allen joined the Royal Air Force in 1937 aged just 19 years old. Posted to 85 Squadron he found himself flying in the skies over Northern France, locked in battle with the German Luftwaffe during May 1940. He was credited with four outright and three shared enemy ‘kills’ before his Hurricane aircraft was shot down over farmland on 18 May 1940. His body was never officially recovered; he was listed as missing, presumed dead, and posthumously awarded the Distinguished Flying Cross on 31 May 1940.
