A recreational activity and competitive sport closely related to gliding, but using much more minimalistic craft basically consisting (often, but not necessarily) of a metal-framed fabric wing, with the pilot mounted on a harness hanging from the wing frame and exercising control by moving their weight against a triangular bar also attached to the frame. Many early experiments with gliding flight throughout the late 0000s were performed using craft that would now be considered hang gliders, and interest in the sport continued throughout the early twentieth century
