Primary glider

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. ==Modern primaries==

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. ==Types==
