De Havilland Heron - Definition and Overview

The de Havilland DH.114 Heron was a small, propeller-driven British airliner that first flew on May 10 1950. It was a development of the de Havilland Dove, with a stretched fuselage and two more engines, for a total of four.

The Heron was of all-metal construction, and was laid out as a conventional, low-wing monoplane with tricycle undercarriage. 150 were built, exported to around 30 countries. Herons later formed the basis for various conversions, such as the Riley Turbo Skyliner and the Saunders ST-27 and ST-28.
