By controlling the flow of the air over an airfoil, a lifting force can be achieved even in the absence of forward motion by the aircraft. The air flowing over the airfoil is forced into a chamber by a propulsion unit and the air entrapped in the chamber can be recirculated to a forward portion of the airfoil lifting surface, thereby increasing the lifting force of the airfoil. The lifting body has side members associated with the airfoil to channel the air over the airfoil. Outlets from the chamber are provided to direct the flow of air in any lateral direction for assistance with directed motion or for assistance with aircraft stability. Additionally, outlets in the bottom of the aircraft can assist in the vertical force exerted on the aircraft by forced air escaping therefrom.
