Description Dr. Bothezat constructed a vertical flight machine in 1922 for the US Army Air Corps. It was built around an X-shaped structure with a 6-bladed rotor at the end of each of the arms. The machine made around 100 flights and achieved a maximum hover height of 11 feet. On 18th December 1922 it remained airborne for one minute and 42 seconds. It also held a payload record by lifting four people and the pilot. However, the machine was very difficult to control and the army, which was more interested in autogyros, stopped funding the project.
