Gliders are generally used for flight training and also have the capability to fly acceptable distances when they are catapulted or towed in the air, However they deficiency the dynamic sophistication of sailplanes. These refined unpowered craft have wings of unusually high part ratio (that is certainly, a long wing span in proportion to wing width). Most sailplanes are towed to launch altitude, Whilst some use compact, retractable auxiliary engines.
