Unlike many Fokker triplane reproductions, Mikael Carlson's Dr.I feels like a real WWI war machine. It has an authentic rotary engine, albeit a Le Rhône, and even comes with machine gun sound. It is painted as an aircraft flown by Lt Johann Janzen, a Jasta 6 ace, in February 1918.
Suspended in the museum's cinema, this dusty Dr.I replica still had a valid N number at the time of wirting, like many retired aircraft in America it seems. Note how the registration is concealed as a 1917 German serial.
