The Albatros L 73, a twin-engined biplane airliner from Germany in the 1920s, had a traditional design with a sleek, boat-like fuselage and engine nacelles.
All four planes of this model were used by Deutsche Luft Hansa, with one (Brandenburg, D-961) crashing near Babekuhl on May 28, 1928.
Subsequently, these aircraft were sold to the Bulgarian Air Force to be used as bomber trainers.
