Tempelhof airport is chosen as place for additional housing space for thousands of refugees arriving in Berlin in 2015. Berlin is expecting 40,000 refugees under the quota system. Housing space is hard to find to accomodate refugees arriving in large numbers in September 2015. The airfield has been preserved by conservationists as a place for children to play frisbee and as outdoor park space. Now the hangars at Tempelhof can be used to create housing space as winter approaches and tents become inadequate. During the Berlin Airlift 200,000 flights by the air force of U.S., Britain, Canada, Australia, South Africa, participated in sending food and medical supplies to the people of Berlin when the Soviets blockaded Berlin on April 1, 1948 till May 12, 1949. It was lifted when it was clear as much in supplies were delivered by air as before the blockade. As this time Germany takes on a similiar humanitarian challenge the memories of that period provide inspiration for the effort.
