On June 26, 1948, U.S. and British pilots begin delivering food and supplies by airplane to Berlin after the city is isolated by a Soviet
Union blockade.

When World War II ended in 1945, defeated Germany was divided
into Soviet, American, British and French zones of occupation. The
city of Berlin, though located within the Soviet zone of occupation,
was also split into four sectors, with the Allies taking the western
part of the city and the Soviets the eastern. In June 1948, Josef
Stalin’s government attempted to consolidate control of the city
by cutting off all land and sea routes to West Berlin in order to
pressure the Allies to evacuate. As a result, beginning on June 24
the western section of Berlin and its 2 million people were deprived
of food, heating fuel and other crucial supplies.
