A ground-air-water craft comprises a fuselage body with a passenger compartment mounted thereon, a box-type main wing connected to the fuselage and extending outwardly on both sides thereof, the main wing comprising an upper wing and a lower wing which are substantially horizontal and which have a total wing span in the range of 5 to 10 feet, as well as a right side member and a left side member, each side member extending substantially vertically and connected between the lateral ends of the upper and lower wings on the respective right and left sides of the craft. The craft also comprises a control or canard wing connected to the fuselage and extending outwardly on both sides of the fuselage with a wing span no greater than 10 feet. The craft also comprises front and rear wheels with balance wheels mounted therebetween, air propelling means which may constitute a propeller or a jet engine mounted on the craft, water propelling means driven by a hydraulic or electric drive motor, and fuel tanks mounted in the upper wing. The control wing is pivotable about its longitudinal axis, and all of the wings have moveable control surfaces comprising flap means for controlling the lift as well as air spoiler means disposed on the upper surfaces thereof. The front and rear wheels may be retractable and the body portion of the fuselage is water tight and includes a hydroplane bottom surface for a reduced resistance to water.
