Scene of the crash of Messerschmitt (Bayerische Flugzeugwerke/BFW) M 27 b D-1979, Werknummer 539. The M 27, designed by Willy Messerschmitt, was a sports, travel, and training aircraft, produced in limited numbers in 1931/32. As can be clearly seen, the M 27 b was powered by an Argus As 8 A-3 inline engine (the M 27 a was powered by a Siemens Sh 12).
M 27 D-1979 was flown by Theodor "Theo" Croneiss on the occasion of the Deutschlandflug 1931.
The inscription on the rear of the photo places this event near Königsberg and states "1929" as the year in which the picture was taken. Given that the M 27 was actually produced after 1929, however, the actual date of the event is possibly 1932. (German Aviation 1919-1945 collection)
