Summary[edit]
| Description |
William Beeson and his published instructions in 1887 held nearly all the mechanical principles and function of later developed hang gliders. Careful reading of the instructions by those skilled in hang glider arts will find delightful instructions. Beeson provided for several flight control methods in kiting and free-flight gliding of persons operating from the control trapeze. The simplified 1908 Breslau cable-stayed control frame with pilot mass hung behind the triangle control frame illustrated Beeson instructions. |
