There are two commonly used options to transport large-volume and heavy cargo across the ocean: container ships and airline transport aircraft. Container ships take about 3 to 4 weeks to deliver goods, and airline transport aircraft take about 2 days. This innovation is a flying boat aircraft designed for heavy lift cargo utilizing wing in ground (WIG) effect. The wing in ground effect has many names, but it refers to the phenomenon where an aircraft flying close to the ground has increased lift and decreased induced drag. The induced drag of the aircraft is half of the induced drag compared to flying at altitude when the aircraft operates within 10% of its wingspan to the surface. The lift is double compared to flying at altitude when the aircraft is operating within 10% of its chord length to the surface.
