It was a time when the American and British air forces supplied the city of West Berlin with everything it needed to survive -- everything from food to coal. It all had to be flown in.he reason it happened is that the Russians had cut off access from the Allied zones of occupation in West Germany to West Berlin, which was in the Russian zone (what became East Germany). So the Allies had to either surrender West Berlin or they had to supply it by air.
