Like others a pleasure flight in a DH Dragon Rapide, mine was in 1979 from Biggin Hill and included local sights like Chartwell. My Mother, who has only recently died (September) had flown in a BEA example from Lands End to the Scillies c1957.
IIRC they remained in service on that route until the S61 helicopter arrived in 1964. That would be well within my lifetime.
