The Macchi M.24 was a flying boat produced in Italy during the 1920s. Originally intended as a bomber, it was eventually produced for civilian use as well. The M.24 resembled a scaled-up version of earlier Macchi flying boat bombers such as the M.9 and M.18, sharing their biplane configuration and Warren truss-style interplane struts. However, while these earlier aircraft were single-engine types, the M.24 had twin engines mounted in a tractor-pusher pair on struts in the interplane gap.
