Abstract: An aircraft capable of vertical short takeoff and landing is shown according to the teachings of the present invention as including four separate engine locations. In its most preferred form, the first and second engines are located on opposite sides of the fuselage of the aircraft and are pivotal about first and second axes which are in a plane perpendicular to the longitudinal axis of the aircraft and which are in front of the center of gravity of the aircraft. The third and fourth engines are located on opposite sides of the fuselage of the aircraft and are pivotal about third and fourth pivot axes which are parallel to the first and second axes of the first and second engines, respectively, but which are behind the center of gravity of the aircraft. The engines are mounted and rotated about their respective pivot axes by a system including a shaft having a first end operatively attached to the engine.
