I once flew into Moscow and the Flight Engineer wished us a cheery farewell as we boarded the crew bus to the hotel. I asked him where he was going? He replied that he was 'A Hero of The Soviet Union' and was being picked up and taken care of for the slip.
On our return I questioned him and he explained that he was on the Arctic convoys during the war taking essential supplies to the Soviets to assist in their battle against the Nazis.
I don't know exactly what he did, either in the convoy or, indeed, during the Moscow slip.
Anyone out there remember this EO?
