In June 1948, the Soviet Union closed off all surface access into the city of Berlin, Germany to challenge control of the city which had come to be occupied by the countires of the U.S., the U.K. and France. Avoiding conflict on the ground to free the blockade - and fearing another World War - the allies instead built an "air bridge" or "Luftbrucke" into Berlin, flying C-47's and C-54's from Rhein-Main Air Base to deliver food and supplies for "Operation Vittles" sustaining the city's 2 million citizens for a remarkable 15 months and peacefully ending the blockade.
The Berlin airlift was arguably air power's single most decisive contribution to the cold war and it unquestionably achieve a profound strategic effect.
In 41 months between July 1992 and January 1996, international airlift flew nearly 200 thousand tons of aid supplying the city of Sarajevo during Operation Provide Hope. This total number was easily surpassed during one month of flying during March 1949 for Operation Vittles where Allied flyers delivered a total of 2.3 million tons.Berlin Airlift Video
