I flew on what must have been one of the very last scheduled DC6 passenger services in Europe. It was July 1978 and the flight was between Ponta Delgada and Terceira in the Azores, operated by the local airline SATA. It should have been one of their newly delivered HS748s, the DC6s having been retired from frontline service a couple of months previously but for whatever reason they dusted off the old girl and pressed her into service. Wonderful flight.
