The question is in one scene the British Intelligence officer who is Army is seen wearing RAF wings, did the Army pilots during the war wear the same wings?
The intelligence officer is Lt Col Dudley Clarke.
Born in Johannesburg and brought up near London, Clarke joined the Royal Artillery as an officer in 1916 but transferred to the Royal Flying Corps after finding he was too young to fight in France.
