I flew in the Cranfield Doves during a flight testing course as part of my Aero Eng degree from London QMC. Great fun and a brilliant course - I learned more in 2 weeks there than in 4 years at QMC! Apparently one of the Doves had belonged to Emil Savundra, an infamous swindler of the '60s! The Doves weren't particularly noisy as I recall - unlike the loathsome Jestreams on which I suffered 15 hours of misery doing a multi-engine refresher course in the RAF.
When Lulsgate became Bristol Airport in 1957, Jersey Airlines Herons were a common sight along with various other propeller-engined airliners as until the late '60s, the runway was too short for jets.
