 With Bangkok, Hanoi and Taipeh, further Asian destinations were added to the route network.During the 1930s, Luft Hansa aircraft had also been deployed on a number of experimental and survey missions, most notably for developing the best airborne crossing of the South Atlantic, and during the Third German Antarctica Expedition in 1938-39, when two Dornier Wal aircraft performed a photographic survey of 350,000 square kilometres, an area which became known as New Swabia.With the outbreak of the war on 1 September 1939 all civilian flight operations of Luft Hansa came to an end, and the aircraft fleet came under command of the Luftwaffe, along with most staff.
