X-Plane 9.70+ SIAI-Marchetti S-55. The Savoia-Marchetti S.55 was a double-hulled flying boat produced in Italy beginning in 1924. Shortly after its introduction, it began setting records for speed, payload, altitude and range. Even though its design was unusual, the Savoia-Marchetti S55 was a remarkably airworthy craft. The Savoia-Marchetti S.55 made a number of early crossings of the Atlantic Ocean at a time when doing so was still a very risky and challenging venture, starting when the Plus Ultra, a Spanish Dornier Wal piloted by Ramon Franco, crossed from Spain to Buenos Aires, Argentina, in January 1926, then Santa Maria under Francesco de Pinedo took off from Dakar, Senegal to Pernambuco, Brazil on 13 February 1927.
