Primary glider

Primary gliders are a category of aircraft that enjoyed worldwide popularity during the 1920s and 1930s as people strove for simple and inexpensive ways to learn to fly.

[1] Constructed of wood, metal cables and cloth, primary gliders were very light and easy to fly.

The ends of the rope were pulled by hand to launch the glider from a slope.

Primaries were also launched by auto-tow and auto-bungee tow.

[1] Modern versions of primary gliders are still built, but, while they are much like the originals in appearance, they are usually constructed with composites and safety enhancements.
