On 8 May 1945, Western Allied and German signatories of the German Surrender in Berlin and their entourage landed at Tempelhof airport. At the beginning of May, Weser Flugzeugbau opened a workshop in hangar 7 to repair streetcars. In the following weeks, Berliners raided all unguarded parts of the opened buildings searching for food or anything else useful in bartering in the black market. In accordance with the Yalta agreements, Zentralflughafen Berlin-Tempelhof was turned over to the United States Army 2nd Armored Division on 2 July 1945 by the Soviet Union as part of the American occupation sector of Berlin. This agreement was later formalised by the August 1945 Potsdam Agreement, which formally divided Berlin into four occupation sectors.
