The History and Mechanics of Hang Gliding
TLDR Hang gliding has a rich history dating back to the 1940s and experienced a reinvention in the 1970s. Hang gliders are simple machines consisting of an airfoil, and the sport involves using gravity and drag to generate lift and stay aloft.

Hang gliding is the topic of discussion in this podcast episode of "Stuff You Should Know."
04:49
Hang gliding has a history that dates back to the 1940s, with NASA engineer Francis Rogalow's idea to use a crude hang glider as an alternative to parachutes for returning spacecraft to Earth.
09:32
Hang gliding experienced a reinvention in the early 1970s, with the design of foot-launched hang gliders and the formation of companies like Wills Wing, which helped grow the sport in the 70s and 80s.
14:17
Hang gliders are simple machines, consisting of an airfoil, and there is not a significant difference between old school flexible wings and newer rigid wings.
18:57
Hang gliders consist of a fabric-covered skeleton made of aluminum or carbon fiber tubes, with wires connecting and stabilizing the structure, a control bar for steering, and a harness for the pilot.
23:50
Hang gliding involves lying on your stomach and hanging from a hang glider while using a control bar to steer, and launching off a cliff or ramp to generate lift and counter gravity.
28:29
Gravity and drag are the main factors in hang gliding, with drag slowing you down and gravity helping you move forward, and the ability to catch air currents is what allows hang gliders to stay aloft for long distances.
33:19
To control the hang glider, you shift your body left and right and tip the nose up and down, with tipping the nose down to go up and tipping the nose up to slow down and land, and it's important to remain calm and relaxed while flying.
38:10
Hang gliding can be compared to running downhill and using the hang glider to stabilize yourself so that your legs don't get ahead of you, and once you find that balance, the weight is transferred from your feet to the straps of the harness, allowing you to take off and soar.
42:19
The earliest hang gliding designs didn't use a harness, but rather had the hang glider lift off and the person would hang from the control bar, similar to a zipline.
