including interned Polish Lockheed 14, two Junkers Ju 52 of AGO and PTO-4 trainer aircraft of Estonian Airclub, were relocated to Lasnamäe Airfield. During the German occupation, regular international connections were announced on 16 October and already restored on 15 November 1941, when Deutsche Lufthansa and Aero O/Y started the route Helsinki-Tallinn-Riga-Königsberg-Berlin. From 1942 to 1944 Sonderstaffel Buschmann was based at Tallinn Airport. Soviet period Between 1945 and 1989, Aeroflot was the only airline that served Tallinn Airport. The construction of the new passenger terminal, which was put on hold due to war, resumed. The building, which was redesigned in accordance with the Stalinist architecture, was finished in 1954 and commissioned on 7 November 1955. Regular flights with jet aircraft began on 2 October 1962 with a maiden passenger flight from Moscow with a Tu-124, which was the latest Soviet airliner. As the terminal built in 1954 became obsolete and unable to cope with growing airport traffic, the construction of the current terminal building began in 1976 and the terminal was opened in 1980, prior to the 1980 Summer Olympics sailing event, which was held in the city. The architect of the new terminal was Mihhail Piskov, who took visual inspiration from traditional Estonian housebarns, and the interior designer was Maile Grünberg. The runway was also lengthened then. The first foreign airline since World War II to operate regular flights from Tallinn was SAS, whose first flight to the airport took place on 25 November 1989. Modern development The construction works of the first cargo terminal (Cargo 1), located in the middle of future cargo area on the north side of the airport, were carried out from September 1997 until March 1998. The passenger terminal building was completely modernised in 1999, increasing its capacity to 1.4 million passengers per year and after that greatly expanded in 2008. The growing demand for extra space for cargo operations, created a situation where there was need for cargo terminal expansion, Cargo 2. In order to meet the growing demand for new cargo facilities at Tallinn Airport, the number of cargo terminals was later expanded to four. In year 2012 a new aircraft maintenance hangar was opened and a number of passengers passed two million mark the first time in the history of the airport. On 11 January 2013 the airport was accepted into Airport Carbon Accreditation emission managing and reduction programme by ACI.
