SIAI S.9

The SIAI Savoia S.9 was an Italian reconnaissance flying boat, manufactured by Societa Idrovolanti Alta Italia (S.I.A.I.) from 1918. The wing structure was unusual by being a single-bay biplane wing, with additional struts mounted mid-bay at the junction of the flying and landing wires, so that it appeared to have a two-bay wing. The S.9 was also licence-built in France by CAMS (Chantiers Aéro-Maritimes de la Seine) as the CAMS C.9.
