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. They generally had no cockpit and no instruments.[1]
Operations
[edit]Primary gliders were generally launched by bungee cord, whereby a rubber rope was arranged in a "V" with the glider at the apex. 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. Ramp launching from cliffs was also attempted successfully.[1]
Modern primaries
[edit]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.
