Unlike the director of the 2006 movie Flyboys, who filled the screen with dozens red Dr.1s, most people know there was only one all-red triplane - the Red Baron's.
Fokker Dr. 1 Replica
This Dr.1 replica is owned by Vintage Aero Flying Museum. It's powered by a Lycoming 180 hp radial engine. Of course, this all red triplane depicts the mount Manfred von Richtofen flew. The Dr-1 was a difficult aircraft to fly. It required extreme concentration due to its limited visibility and its unstable flight characteristics.
