A veritible fly-tilla of Dubena-Cesky airliner models...
Back row - 3 Douglas DC-7s and a De Havilland Comet - Front row - 2 Convair CV-880s - Boeing 707 - Sud Aviation Caravelle
DC-7s seem to be the most readily available and are often bundled with the plane I specifically wanted to get. The silver one had cosmetic damage requiring a spritz of paint.
