Hybrid, including accessories

A hybrid is a combination of the above mentioned categories. Examples could be VTOL (Vertical Tak.off and Landing), i.e. the fixed wing ability to generate lift in combination with the helicopter or rotor copter ability to hover and start/land vertically. But a hybrid could also be that the fuselage can be refined into all three categories by replacing wings with rotors or adding rotors or wings to the fuse-lage.
