Halvorsen was one of the pilots who, a few years after the Second World War, supplied the western part of Berlin, which had been sealed off by the Soviet Union for ten months, with food and coal, among other things, by air. The blockade ended exactly 73 years ago, on May 12, 1949. It was Halvorsen's idea to also drop candy for children on small parachutes during the Berlin Airlift. As the "Candy Bomber," the young pilot became a symbol of the relief effort. His numerous awards included the Federal Cross of Merit.
