The hang glider is controlled by weight shift. By moving the position at where your body hangs allows us to alter the balance of the glider, which allows it to go where we want. You will be surprised at how much control this gives us.
If you like you are welcome to try flying the glider yourself after launching.
No experience is required because the whole Flight is done under the full control of the pilot. The only things the passenger has to do are running about 7 steps during take off.
