Alan Rodgers was a member of RAF Ferry Command. He made 10 transatlantic crossings for the service during the war. West-bound they would either be by ship or air, the latter probably in an unpressurized Liberator or Lancaster bomber, wrapped for warmth against the freezing cold. East-bound he was flying in a Consolidated PBY ‘Catalina’ flying-boat from Elizabeth City, North Carolina first to Bermuda then on the much longer leg to Scotland.

nacelle area between the wing and main fuselage, the position of the Flight
Engineer.
