McGlashan was the son of a general practitioner of Scottish origin who had a passion for the sea; he was drowned during the Second World War when the Domala, on which he was serving as ship's surgeon - after lying about his age - was bombed. Alan was educated at Epsom College before entering the RFC (later the RAF) at a tender age during the First World War, and flying many perilous missions, including two aerial encounters with the "Red Baron", the German ace Baron von Richthofen. McGlashan was awarded the MC and the Croix de Guerre avec Palmes, and was frequently mentioned in dispatches.
