Maiden flight of the de Havilland DH.90 Dragonfly, a British twin-engined luxury touring biplane.
Development
The Dragonfly shares a clear family resemblance with the Dragon Rapide, but is smaller and has a higher aspect ratio, slightly sweptback wings. The lower wing has a shorter span than the upper, unlike the DH.89, and the top of the engine nacelles protrudes much less above its surface because the fuel tank had been moved to the lower centre section. Structurally, too they are different: the Dragonfly has a new preformed plywood monocoque shell and strengthened fuselage. It is designed as a luxury touring aircraft for four passengers and a pilot, with provision for dual controls. The first aircraft, G-ADNA, first flew on 12 August 1935. The Dragonfly achieved maximum performance on low power, by using the new construction methods developed for the de Havilland Comet racer.
