It could have been the start of World War III. Instead, it became the largest humanitarian campaign the world had ever seen. On June 24, 1948, one of the first major crises of the Cold War occurred when the Soviet Union blocked railroad and street access to West Berlin. For nearly a year two million civilians and twenty thousand allied soldiers in the city's western sector were fed and fueled entirely from the air. Former German soldiers built airfields and repaired engines for the enemies they had been shooting out of the sky just three years before. British and American pilots, so recently delivering death, were now angels of mercy, supplying coal and flour, coffee and chocolate to the beleaguered city. Through lavish re-enactments and the personal stories of those who lived through the airlift, this American Experience production provides a dramatic and striking portrait of the first battle of the Cold War.
