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.

A land, air and water (“LAW”) craft having a center of gravity and comprising, in combination: (a) a fuselage having a front end, a rear end, and a passenger compartment therebetween, said fuselage defining a central, longitudinal and vertical plane between said front and rear ends; (b) a box-type, main wing connected to said fuselage and extending outwardly, on both sides of said fuselage, approximately equal distances from said longitudinal plane, said main wing including (i) an upper main wing and a lower main wing which are substantially horizontal and have substantially the same wingspan, between opposite lateral ends, said lower main wing extending from a leading edge, which is rearward of the driver\s position in said passenger compartment, to a trailing edge which substantially coincides, in longitudinal position, with said rear end of said fuselage, said upper main wing having a leading edge which is forward of said leading edge of said lower main wing; and (ii) a right side member and a left side member, each side member extending substantially vertically and connected between said lateral ends of said upper and lower main wings on a respective right and left side of said craft; (c) a control wing connected to said fuselage and extending outwardly, on both sides of said fuselage, approximately equal distances from said longitudinal plane, said control wing and said main wing being located, with respect to each other, such that their centers of lift are on opposite sides of said center of gravity as viewed in the direction of said longitudinal plane; (d) front wheel means mounted on said craft forward of said center of gravity; (e) rear wheel means mounted on said craft to the rear of said center of gravity and beneath said lower main wing at such longitudinal position that it prevents said lower main wing from contacting the ground when said craft is flying at an extreme upward pitch; (f) prime mover means mounted on said craft; (g) air propelling means mounted on said craft between said two side members and above said lower main wing; and (h) first coupling means for selectively coupling said prime mover means to: (i) at least one of said wheel means, and (ii) said air propelling means.
