In 1947 the Cold War got colder and the Russians tried to isolate Berlin from the West by cutting all land communications. The Allies now had the problem of sustaining the population of Berlin during the winter of 1947-48 - one of the coldest on record. The answer was the Berlin Airlift - code-named Operation Plainfare. This is the complete narrative of that operation. Highly recommended, particularly for its detailed treatment of the whole operation.
