During late 1933, a team at de Havilland, led by aircraft designer Arthur Ernest Hagg, began working on a new design, intended to be a faster and more comfortable successor to the earlier DH.84 Dragon. The new aircraft was, in effect, a twin-engined, scaled-down version of the four-engined DH.86 Express. It shared many common features with the earlier DH.86 Express, including its tapered wings, streamlined fairings and fuselage, as well as the same Gipsy Six engines. However, the DH.89 demonstrated none of the operational vices of the Express.
