Langdon was present at D-Day, and after the Second World War, became a vicar in the Church of England, being noted for baptising the future Dean of Ripon (John Dobson), who would later become his boss.
The family decided to move back to England for a "more comfortable experience" and Langdon was educated at Oundle School and joined the Royal Marines in 1942.
Langdon helped one wounded survivor, but returned to his cabin to retrieve his bible and some tennis rackets; he was later rescued by the Empire Battleaxe.
