dealter kites are the olny ones
Otto Lilienthal (1848-1896) was one of the first men to fly. He designed, built, and flew many different designs of gliders. His gliders were designed to be controlled by shifting his weight, just like modern hang gliders. He died flying one of his powered gliders. The Wright brothers were inspired by his bi-plane designs.
