I'm not sure what the right terminology is, but there are also gliders like this: https://youtu.be/OpemglwS8XA?feature=shared https://youtu.be/OpemglwS8XA?feature=shared Which are a step up from even the most sophisticated "hang glider", assuming that hang glider refers to the kite type thing that you hang underneath and steer with body weight shifting. I'm pretty sure even the best paragliders aren't anywhere near 40:1 L/D ratios.
