DescriptionThe Bristol Type 170 Freighter was a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner.
It's best known use was as an air ferry to carry cars and their passengers over relatively short distances. A passenger-only version was also produced, known as the Wayfarer.
The Freighter was developed during the Second World War, having attracted official attention from the British Air Ministry, which sought the development of a rugged vehicle capable of carrying various cargoes, including a 3-ton truck. Various changes to the design were made to accommodate their requirements, but being completed too late to participate in the conflict, the majority of sales of the Freighter were to commercial operators. In response to customer demand, an enlarged version to maximise vehicle-carrying capacity, known as the Bristol Superfreighter, was developed.
The Bristol Type 170 Freighter was a twin-engine, high mounted-wing monoplane that was developed specifically for the economic carriage of freight by air. It was a visually distinctive aircraft, possessing a 'boxy' fuselage, rounded nose, and a high-set flight deck.
The lower nose of the Freighter was covered by a pair of large clamshell doors, for easy access to the main hold; as a direct consequence of this arrangement, the unpressurised fuselage was somewhat breezy during flight. The doors, which are hinged outwards, led into a main hold that had an internal volume of 2,020 cu ft; it was capable of being loaded with heavy payloads, up to a maximum of 350 cu ft per ton.
Bristol 170 Freighters were operated in Australia by Ansett ANA,, Ansett MAL, Air Express and TAA, and the RAAF.
