a heavier-than-air flying machine similar to an airplane, but without an engine. It is typically towed to a high altitide by a powered aircraft and then glides to earth with no other source of power.

A fixed-wing aerodyne intended for motorless flight. Gliders are generally divided into four classes: (1) Primary Glider. Used for training and designed for simple glides with continuous loss of height. (2) Intermediary Sailplanes. A more advanced form of glider capable of continuous flight without loss of height. (3) High Performance Sailplanes. A highly developed glider of great aerodynamic efficiency designed for competition and other high performance flying. (4) Towed Glider. This is towed behind an aeroplane singly or in a "train" carrying troops or freight.

Corvette assembled at St. Louis with no engine or transmission.

A non-power-driven heavier-than-air aircraft that derives its lift in flight from aerodynamic reactions on surfaces that remain fixed during flight. Fr: planeur

an aircraft without an engine. Gliders are towed into the air by a powered aircraft or by a towline attached to a winch on the ground, and soar higher on rising currents of air

A heavier-than-air aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces and whose free flight does not depend principally on an engine. An example is the Nimbus III

aircraft supported only by the dynamic action of air against its surfaces

a aircraft that only uses the wind to keep it in the air and for moving it through the air

a fixed-wing aircraft deigned to use air currents for normal lift, although it may have an engine

a heavier-than-air aerodyne which is supported in the air by aerodynamic reactions and is not provided with mechanical means of propulsion

a high performance motorless aircraft which is designed to have a very flat glide angle

an aeroplane without an engine

an unpowered aircraft - an airplane without a motor

an unpowered aircraft and is about as close as humans can get to soaring like birds

an un-powered vehicle (for which no fuel is required), the flight of which is based essentially on gravity and aerodynamics

a plane that travels through air unpowered

a simple unpowered type of aircraft

a type of metal flying dragon which moves through the air because the wind pushes it

a very high efficiency aircraft designed with an exceptionally flat glide angle and no mechanical means of propulsion

an airplane that is towed into the air then released. a glider has a pilot and control surfaces so it can be 'flown' during its descent.

A highly efficient engineless aeroplane. Capable of flying for long periods in gently rising air currents (thermals).

An unpowered fixed-wing heavier-than-air craft. (See also sailplane)

A fixed-wing, heavier-than-air craft having no engine.

Gliders or Sailplanes are heavier-than-air aircraft primarily intended for unpowered flight. See also gliding and motor gliders for more details.
