I recall flying from Southend to France (Calais?) in the back of a Silver City Bristol Freighter in about 1960. My mother asked when the car would arrive and the stewardess replied: "just before us" and to my mother's horror opened a door on the left hand side of the passenger compartment to reveal 2 cars and a motorbike. As we were taxying out my father enquired what we might do in the event of a ditching in the channel to which the stewardess pointed to a ladder and a roof hatch and told him to open the hatch and use the ladder! Those were the days!
