The present invention provides a tilt rotor aircraft having a centrally mounted tiltable engine and rotor assembly. A turbine or other type of engine (or engines) is pivotally mounted on a central frame above and between the pilot and co-pilot, who occupy separate and identical control cockpit pods on either side of the engine. Placing the engine between the pilot and copilot maintains the CG within a narrow band in both horizontal and vertical flight modes, simplifying control and handling. Counter-rotating propellers may be driven by the engine(s) to eliminate torque effects. By mounting the engine and rotor package between and above the pilot and copilot, the rotor can be made to clear the ground, allowing the aircraft to land like an ordinary fixed-wing aircraft without damaging the propellers. Thus, the craft can be launched and landed in VTOL, HTOL, or STOL configurations, depending upon conditions and available landing and takeoff sites.
