Lioré et Olivier LeO H-190
The Lioré et Olivier H-190 was a flying boat airliner produced in France in the late 1920s. Conventional for its day, it was a single-bay biplane with un-staggered wings, its single engine mounted tractor-fashion underneath the upper wing and supported on struts in the interplane gap. Early examples had the pilot's open cockpit located aft of the wing, but this was later relocated forward of the wing. Developed as a passenger transport, versions of the H-190 were also built as catapult-ready mail planes intended to be launched from transatlantic liners, and as coastal patrol aircraft. The sole LeO H-194 was flown by Marc Bernard together with a CAMS 37 flown by René Guilbaud in a long-distance expeditionary flight across Africa in late 1926. They covered  in three months, covering Morocco, Mali, Nigeria, Belgian Congo, Mozambique and Madagascar. Variants
