Regent Craft Inc. says it recently completed a series of test flights with its seaglider technology demonstrator. The electric-powered, radio-controlled craft with an 18-foot wingspan is a quarter-scale model of a full-size, passenger-carrying prototype that is in the works. It made the flights over Narragansett Bay in Rhode Island.
The seaglider, also known as a WIG, or wing-in-ground-effect vehicle, resembles a seaplane but flies close to the surface in ground effect, which allows it to remain airborne while using less energy than it would flying at higher altitudes.
