Gliders, or sailplanes as they are sometimes known, represent a remarkable fusion of aerodynamics, craft design and human skill. Unlike powered aircraft, gliders rely on the beauty of physics to stay aloft, riding on rising currents of air and the careful management of energy. This article explores how Do Gliders Work, why their design makes…
