Aviation Traders

Aviation Traders was established by Freddie Laker at Rochford Aerodrome near Southend-on-Sea, Essex, England in 1949 and was one of many seeking to develop a successor to the Douglas DC-3 aircraft that had been so prominent during and after the Second World War. The outcome of their work was the ATL-90 Accountant that first flew on 9 July 1957. This was designed for 28 passengers and, like the more successful Avro 748, Handley Page Dart Herald and Fokker Friendship, was powered by two Rolls-Royce Dart turboprop engines. Unfortunately the market was saturated and the Accountant attracted no orders.

Conversion work proved more successful. Some Avro Tudor airliners were adapted with large freight doors to carry cargo for Air Charter Ltd as the 'Super Trader'. Twenty-one Douglas DC-4 airliners were converted to car ferries as the ATL-98 Carvair, a major task that included raising their cockpits high above the original fuselage and hinging a bulbous nose built beneath through which up to six cars could be loaded one at a time by means of a mobile ground-based lift. Twenty-two passengers could be accommodated in the remaining rear fuselage whose cross-section remained as-built. The fin and wings were enlarged to offset the added bulk and weight. Many of these piston-engined Carvair aircraft were operated from Southend Airport on short routes across the English Channel or North Sea. The provision of such fast ferry services by large hovercraft (the SR-N4) and subsequently by Shuttle trains using the Channel Tunnel meant that the age of the car carrying airliner that commenced with the Bristol Freighter, concluded with the unforgettable Carvair. Commercial considerations mean that such an era is unlikely to recur. In 1956, Aviation Traders purchased over 250 surplus ex Royal Air Force Percival Prentice trainer aircraft, a number of which were converted for civilian customers.
