Farman F.50
The Farman F.50 was a French twin-engined night bomber designed and built by Farman as a replacement for the single-engined Voisin pusher biplanes in service with the French Air Force. Development. The twin-engined F.50 flew for the first time in early 1918, powered by two Lorraine 8Bb engines, as an unequal-span biplane with a slab-sided fuselage and a single fin and rudder. It had a fixed tailskid landing gear with twin wheels on the main gear, an open cockpit for the pilot and gunner/observer, and a gunner position in the nose. It  was equipped with a 7.7 mm machine gun forward and aft. The two engines, Lorraine 8Bd V-8s on production aircraft, were mounted between the wings using vee bracing struts. With the Armistice, production was less than 100 aircraft, but the company designed a passenger conversion for civil use, designated F.50P, with the fuselage behind the cockpit raised and enclosed to create a glazed cabin for up to five passengers. One example was used by Compagnie des Grands Express Aeriens from July 1920 from Paris to London and Amsterdam. Operational history. With the military designation Bn.2 (2-seat night bomber) the  aircraft were delivered to squadrons within 1e Groupe de Bombardement. Three escadrilles (S25, F114 and F119) had been equipped by the time of the Armistice in November 1918, with 45 F.50s in service. With the end of the war the aircraft did not have time to influence the campaign and the aircraft continued to serve until at least 1922. Two aircraft were sold to the United States after the war.
