DH114 Heron 2D. Originally developed from the twin-engined DH Dove design, this particular Heron was built in 1956. Powered by four 250 hp de Havilland Gipsy Queen 30 Mk.2 engines, the Heron could carry up to 17 passengers. However, as a Heron 2D, this example had an executive interior, which was quite appropriate given the fact that it was owned and operated by Rolls-Royce. It is on display at the De Havilland Aircraft Museum #RollsRoyce #Dehavilland #aircraft #aviation #excutiveaviation #DHAM #DeHavillandAircraftMuseum #avgeek #museum DH114 #DeHavillandHeron #Heron #pistonengines #GipsyQueenengine #DHDove
