The Dornier Do 17, sometimes referred to as the Fliegender Bleistift ("flying pencil"), was a World War II German light bomber produced by Claudius Dornier's company, Dornier Flugzeugwerke. It was designed as a Schnellbomber ("fast bomber"), a light bomber which, in theory, would be so fast that it could outrun defending fighter aircraft.The Dornier was designed with two engines mounted on a "shoulder wing" structure and possessed a twin tail fin configuration.
