If it's any slight consolation, I consider that the two accidents of the Air Ferry DC4 and British Midland C4 together forced the UK charter airlines to modernise their fleets and move to jet equipment. At the time, there was much press comment about "piston engined charter aircraft" and within 2/3 years most of the holiday airlines had ordered or introduced jets into their fleets. You often saw, in the late 60s/early 70s holiday brochures that emphasised jet travel.
