MODERN GLIDERS ARE AMONG the most graceful and
aerodynamically efficient of all aircraft. Unpowered but with
a large wingspan (up to about 82 ft, or 25 m), gliders use
currents of hot, rising air (thermals) to stay aloft, and
a rudder, elevators, and ailerons for control.
Modern gliders have achieved flights of more King post
