Gliders were developed in the 1920s for recreational purposes. As pilots began to understand how to use rising air, sailplane gliders were developed with a high lift-to-drag ratio. These allowed the craft to glide to the next source of "lift", increasing their range. This gave rise to the popular sport of gliding.
