PFALZ DR-TYP Germany
In the late autumn of 1917, the Pfalz Flugzeug-Werke completed and flew a triplane derivative of the standard D III biplane. Retaining the 160 hp Daimler D III engine, this experimental model (for which no designation is recorded) featured ailerons on both upper and lower wings. It would seem that manufacturer’s trials were unsuccessful, however, as this triplane was never demonstrated to the military authorities at Adlershof.
