The Dornier Do 17, sometimes referred to as the Fliegender Bleistift ('flying pencil'), was a light bomber produced by Dornier. It was designed as a Schnellbomber, a light bomber so fast that it could simply outrun defending fighters. It was used in the first three years of World War II with some success by the Luftwaffe, before being sent to secondary roles and other nations when its performance was no longer up to front line service. A small run of an updated version known as the Do 215 was also produced for export, but ended up in Luftwaffe service. The successor of the Do 17 was the Dornier Do 217.
