An aircraft of variable geometry and certain unique features which allow its operation along the surface of water, ice or the ground under sail power provided by tilting the wings up into a cross-wind to attain sufficient speed to be self launched into gliding flight in two modes -while close to the surface in wind shear, circling and climbing in a regenerative flight path powered by changes in wind speed with altitude until sufficient altitude is attained to soar on rising air currents.
An amphibious glider, operable in both a surface mode and capable of self-launching into a gliding mode, comprising, a hull; an aerodynamic wing mounted on said hull, said aerodynamic wing including means for stabilizing said glider when operating in said surface mode, said means for stabilizing said glider disposed at the ends of said aerodynamic wing; and a hydrofoil mounted with respect to said hull, said hydrofoil being capable of hydrodynamic direction control.
