The maiden flight of the Lilium Jet was still quite unspectacular - the aircraft just showed its ability to take off vertically and hover on the spot. The full-scale, full-weight prototype is powered by 36 all-electric jet engines that allow it to take-off and land vertically. For the transition from vertical to horizontal flight and vice versa, the aircraft tilts four bars with several electric motors and relatively small propellers accordingly. These bars are attached to the wings and the canards. Since the movements about all three spatial axes are controlled by the motors, the aircraft has no conventional control surfaces like elevator, rudder, or ailerons. Only one moving part in the engine is responsible for the safety of the aircraft.
