No. 105 Squadron was a flying squadron of the Royal Air Force, active for three periods between 1917 and 1969. It was originally established during the First World War as a squadron of the Royal Flying Corps and disbanded after the war. Reactivated shortly before the Second World War, it was inactive again after the conflict. During its second existence it was a bomber unit and had the distinction to be the first to operate the de Havilland Mosquito light bomber. During the 1960s it was reactivated again for six years to provide transport support for the British Army in the Aden Protectorate and the Far East.

The de Havilland DH.98 Mosquito is a British twin-engined, multirole combat aircraft, introduced during the Second World War. Unusual in that its airframe was constructed mostly of wood, it was nicknamed the "Wooden Wonder", or "Mossie". Lord Beaverbrook, Minister of Aircraft Production, nicknamed it "Freeman's Folly", alluding to Air Chief Marshal Sir Wilfrid Freeman, who defended Geoffrey de Havilland and his design concept against orders to scrap the project. In 1941, it was one of the fastest operational aircraft in the world.
