For the ground-based observer corps of World War II, see Royal Observer Corps. An air observer is a military aircrew member whose duties are predominantly reconnaissance. The term originated in the First World War in the British Royal Flying Corps, and was maintained by its successor, the Royal Air Force. An air observer's brevet was a single wing with an O at the root. The term is still used in some contexts now, such as police helicopter units. The first recorded RAF kill of the Second World War, on 20 September 1939, was by air observer Sergeant F Letchford, aboard a Fairey Battle, flown by Flying Officer LH Baker.
