The de Havilland DH.89 Dragon Rapide In late 1933, the Dragon Rapide was designed at the de Havilland company as a faster and more comfortable successor to the DH.84 Dragon. It was in effect a twin-engined, scaled-down version of the four-engined DH.86 Express. It shared many common features with the DH.86 Express, including its tapered wings, streamlined fairings and the Gipsy Six engine, but it demonstrated none of the operational vices of the DH.86 Express, and went on to become perhaps the most successful British-built short-haul commercial passenger aircraft of the 1930s
