An aircraft (12) comprising three wings located on either side of the fuselage (14). The forward wing (22) has a downward angle with a curved top and bottom surface. The upper wing (24) is located towards the rear of the aircraft and above the forward wing (22). The lower wing (26) is located below the upper wing (24) and slightly forward and located to the rear and below of the forward wing. The outer ends of all three wings come into contact at one point. The forward wing (22) uses the Coanda effect to increase the airflow across the top surface of the bottom wing. One embodiment of the aircraft has two turbines (58), shaft-coupled to a power source, located on either side of the forward end of the fuselage. Each engine (58) has part of its thrust (63) diverted through and directed by a plenum disposed internal of the Coanda toward both sides of the fuselage so that an equal amount of thrust (63)flows through the duct (65) and over the wings on either side of the fuselage (14).
