The Blériot Bl-115 was a French biplane airliner of the 1920s, best remembered for the part it played in the French exploration of Africa. For its day, it was a large aircraft, mounting one pair of engines on the upper wing and one pair on the lower. First flying on 9 May 1923, the prototype crashed on 23 June, killing its pilot, Jean Casale. A refined version of the aircraft, the 115-bis was flown in June 1924.
