The Dornier Do 29 was an experimental aircraft developed by Dornier Flugzeugwerke and the Deutsche Versuchsanstalt für Luftfahrt (German Aviation Laboratory) in the 1950s, used to test a tilting-propeller system for short takeoff and landing aircraft. The concept was proved to be successful in flight testing, however no further development of the system or aircraft was proceeded with, and at the conclusion of its test program the Do 29 was retired.
