sailplane
Let an agent explain sailplanes and soaring flight, relay design, classes and performance from gliding sources, describe training, competition and safety, and distinguish sailplanes from hang gliders, paragliders and powered aircraft.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain sailplanes and soaring flight, relay design, classes and performance from gliding sources, describe training, competition and safety, and distinguish sailplanes from hang gliders, paragliders and powered aircraft.
A high-performance glider designed for soaring flight, using rising air in thermals, ridge lift and mountain waves to stay aloft and travel long distances without an engine, with long slender wings of high aspect ratio, glide ratios up to 70 to 1 in open class designs, and types from training two-seaters such as the Schleicher K 7 to competition sailplanes such as the Schempp-Hirth Ventus-3, historical and national designs such as the Nihon N-70 Cygnus and Nippi NP-100, and motorgliders; sailplanes are flown in sport, competition and record attempts.
What it is for: Soaring flight for sport and competition.
It can be explain design and soaring; relay classes and performance; describe training and competition; distinguish from other gliders.
Distinguishing features
High aspect ratio wings
Unpowered soaring
Competition classes
Launch by tow or winch
What it looks like
A sleek aircraft with very long narrow wings and no engine.
Physical character
best glide ratio: up to about 70:1 ratio - open class
typical wingspan: 15-30 m
distance record: over 3000 km - wave flights
How it is recognised
High-performance unpowered soaring aircraft
Training, club, standard, 15 m, 18 m and open class sailplanes; motorgliders; historical designs
Hang gliders and paragliders are foot-launched; primary gliders are basic trainers; sailplane is the formal term for glider
