The Bristol Type 170 Freighter was a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner, although its best known use is as an air ferry to carry cars and their passengers over relatively short distances.

The Bristol Type 170 was designed to Air Ministry Specifications 22/44 and C.9/45 originally as a rugged, heavy-duty transport to operate from unimproved airstrips. After the end of the Second World War the design was adapted by the Bristol Chief Designer A.E. Russell and his design team as a rugged, heavy-duty aircraft. It was an all-metal, twin-engine high-wing monoplane and built without the use of expensive alloys and with a minimum of machined parts. The square-sectioned fuselage was designed to be clear of internal obstructions. The flight deck was high in the fuselage nose, accessed via a ladder.

The Freighter was a somewhat bulbous and cumbersome-looking aircraft. Like the more slender prewar Bombay, it was a high-wing monoplane with fixed undercarriage, the main gear legs supported by substantial vertical struts beneath the Bristol Hercules radial engines and horizontally from the lower edge of the (slab-sided) fuselage. The cockpit sat atop the forward fuselage, with two large clamshell doors in the nose, making the unpressurised fuselage somewhat breezy; one Kiwi pilot claimed his charge was "40 thousand rivets flying in close formation."

Bristol ⁱ/ˈbrɪstəl/ is a city, unitary authority area and ceremonial county in South West England, with an estimated population of 433,100 for the unitary authority in 2009, and a surrounding Larger Urban Zone (LUZ) with an estimated 1,070,000 residents in 2007. It is England's sixth and the United Kingdom's eighth most populous city, one of the group of English Core Cities and the most populous city in South West England.

Historically within Gloucestershire, the city received a Royal Charter in 1155 and was granted County status in 1373. From the 13th century, for half a millennium, it ranked amongst the top three English cities after London, alongside York and Norwich, on the basis of tax receipts, until the rapid rise of Liverpool, Birmingham and Manchester during the Industrial Revolution in the latter part of the 18th century. It borders the counties of Somerset and Gloucestershire, and is also located near the historic cities of Bath to the south east and Gloucester to the north. The city is built around the River Avon, and it also has a short coastline on the Severn Estuary, which flows into the Bristol Channel.
