Answer :
The reason this operation was undertaken by the Americans as ordered by Harry S. Truman was to provide supplies to a blockaded city.
Why did Truman order this operation?
In 1948, the Soviets attempted to block West Berlin in a bid to get the Americans to concede to some of their demands.
President Truman then ordered the Berlin Airlift which saw a plan landing every 3 minutes to ensure that West Berlin received all the supplies it needed regardless of the blockade.
