As this access was closed, in the so-called Berlin blockade, an airlift remained the only option to get increasingly urgent deliveries of food, coal, and other supplies to West Berlin. Over 330 days to 12 May 1949 a total of 2.26 million tons of cargo were airlifted to Berlin, an average of 6,800 tons a day, 80% by the US and 20% by the UK. Although freight traffic developed modestly, reaching only 800,000 tonnes worldwide by the mid-1950s, the world economy was hitting its post-war stride. Germany and Japan were emerging

Stocks of coal, the main source of power for German industry, rose from a low of 186,000 tons kept at the mineheads in July 1944 to 2,767,000 tons in February 1945.

It is estimated that production fell by 22 percent between May 1944 and January 1945. Of this
