A ducted air flow vehicle including a fuselage having a longitudinal axis, a first cockpit on one side of the longitudinal axis, a center portion adjacent and below the first cockpit, a first air flow duct mounted in the fuselage and including a first prime air mover to force surrounding air flow through the first air flow duct, and a second air flow duct mounted in the fuselage and including a second prime air mover to force surrounding air flow through the second duct, where outer upper and lower surfaces of the center portion are aerodynamically shaped to enhance production of aerodynamic lift forces by air flowing over the center portion and reduce resistance to air flow exiting the first airflow duct. |
