The B.Z.308 was a four-engined civil transport developed in the late 1940s for operation over both European and transatlantic routes. A large low-wing monoplane of all-metal construction, it was powered by four
Bristol Centaurus radial engines driving five-bladed propellers. It had a large tailplane with endplate fins and rudders, and had retractable landing gear. The fuselage, oval in cross-section, accommodated a flight crew of five and 55 passengers in two cabins; a high-density model was planned with seats for 80. Construction began during 1946, under aircraft designer
Filippo Zappata at Breda's Sesto San Giovanni works. The
Allied Commission halted the work, which was not resumed until January 1947. Further delays in the delivery of
Bristol Centaurus engines delayed the first flight, which was on 27 August 1948, piloted by
Mario Stoppani. Although flight testing went well, the project was abandoned as a result of financial problems, and anticipated competition from
American airliners in the postwar market. Breda subsequently stopped producing aircraft entirely. ==Operational history==
