What problems did the americans and british have to overcome to carry out the berlin airlift?

In commit to break the blockade, US and British officers started the lift to fly food and provides into city district. This happened as a result of Stalin closed all highways and rail routes into city district, so no food or fuel may reach that part of town. 2.1 million Residents of that town had barely enough food to last for five weeks that the U.S. felt the requirement to assist out. This conflict terminated as Berlin survived entirely attributable to the airlift. This conjointly boosted yank status round the world. Attributable to this, the Soviet Union raised the blockade in 1949.
