The Dornier Aerodyne[1] (also referred to as "Lippisch-Dornier Aerodyne"[2]) was a wingless VTOL unmanned aircraft. Conceived by Alexander Lippisch, it was developed and built by Dornier on behalf of the Federal German Ministry of Defence (BMVg). Lippisch was part of the team.[2] The first flight took place on 18 September 1972. The development ended on 30 November 1972 after successful hovering-flight testing with the aircraft. Experimentation did not continue due to lack of interest by the Bundeswehr (German Armed Forces).[citation needed]
