context: In 1947, a tense diplomatic and military standoff began to unfold between the United States, the United Kingdom and the Soviet Union over the future of Germany. The Americans and Western European allies wanted to include the sectors of Germany which they controlled in the Marshall Plan, an economic plan to rebuild Europe after the devastation of the war. The Soviets perceived the Marshall Plan to be the foundation for an anti-Soviet alliance and pressured the Americans, British and French to back down. On 20 March 1948, the Soviet representative walked out of the meeting of the Allied Control Council, and on 31 March 1948, the United States Congress approved funding for the Marshall Plan. Soviet troops then began to block the corridor that brought supplies from the western zones of Germany to West Berlin. In response, an increased number of aircraft brought supplies by air from west Germany to Tempelhof airfield in the American sector and Gatow airfield in the British sector of Berlin. At the same time Soviet military aircraft began to violate airspace in West Berlin and harass (or what the military called "buzz") flights in and out of West Berlin. Despite the danger of flying in such conditions, civilian aircraft continued to fly in and out of Berlin.
response: Tempelhof, Gatow
