Design and development
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, anticipated competition from American airliners in the postwar market, and pressure (under the Marshall plan) to close down Breda’s aeronautical section. Breda subsequently stopped producing aircraft entirely.
Operational history
The prototype B.Z.308 was acquired by the Italian Air Force in 1949 as a transport aircraft (MM61802).
Despite orders in 1950 from India, Argentina and Persia, only the prototype was built, allegedly also due to pressure from the allies for Italy to refrain from competing in civilian aircraft manufacture after the war.
On 27 August 1948 the Bz 308 made its maiden flight, in front of civil and military authorities, politicians and the Italian President.
The prototype, which passed to the Italian Air Force in 1950 was used to fly between Rome and Mogadishu until on February 21, 1954, when it damaged beyond repair by a collision with a cement truck, it was abandoned in a field in Somalia before being broken up. It was also the first Italian transatlantic aircraft, and the first aircraft to fly into the new Malpensa airport in 1948.
The aircraft is also clearly visible in the airport scene of the film Roman Holiday.
