The Blériot-SPAD S.34 was a French twin-seat, single-engine biplane flight training aircraft designed in 1920. The side-by-side seating arrangement was unique for its time. 150 aircraft were built, 125 for the French Air Force, who used them until 1936.
The Finnish Air Force purchased two S.34s in 1921. Due to inadequate maintenance they did not last long and were withdrawn from service by 1925.
