The Bristol Type 170 Superfreighter Mk 32 was a larger, stretched version of the Bristol Freighter designed for Silver City Airways for use on the short air ferry routes to France.

The first Superfreighters, with a longer - 42 ft 3 in (12.88 m) - hold than the earlier Mark 31, were delivered to Silver City Airways in spring 1953 and were used on cross-channel services to Europe. One example was converted to a 60-seat all-passenger "Super Wayfarer".^[1]

The Mark 32 could carry 20 passengers instead of 12 in the smaller Mark 31 Freighter, and three cars instead of two in its air ferry role.^[2]

The Superfreighter was distinguishable from the earlier Freighter by having a longer nose, in which the extra car was carried, and a fin fillet as well as rounded wingtips.

ABritish United Air Ferries Superfreighter appears in the 1966 comedy film That Riviera Touch as the means by which Morecambe and Wise travel abroad with their car. The aircraft also appears in the 1965 film "Hysteria", and in the 1969 TV series "The Gold Robbers"
