Gerd Achgelis in front of his Fw 44, then a top notch aerobatic aircraft. He came third in the first world aerobatic championships in Paris in June 1934 and then travelled to America for an aerobatic event at the 1934 National Air Races in Cleveland. The reg is confirmed as D-EPIZ. Nazi Germany had two flags at this time and the swastika flag was worn on the port side of the tailfin. Photo by: Rudy Arnold / Smithsonian Institution

The Fw44 was a 1930's biplane, intended for the training and recreational markets. D-2914 seems to have been built in March 1934 and belonged to the Deutschen Luftsportverbandes (DLV) in Bremen. The DLV was set up in March 1933 by the Nazis, to establish a uniform basis for the training of (then civillian) pilots for the future Luftwaffe. Due to the Treaty of Versailles, this was apparently bound to strict rules. Photo from W Muntinga / Focke-Wulf

It is thought to be Sabiha Gökçen, Turkey's first female pilot, who is seen mounting a Stieglitz of the Turkish Aeronautical Association (THK) here. Twenty Fw 44s were delivered to Turkey in 1937.
