Why did Paul Cornu make the helicopter?

Paul Cornu created the helicopter to explore the possibilities of vertical flight and to advance aviation technology. In 1907, he successfully built and flew the first manned helicopter, which featured two counter-rotating rotors. His work was driven by a desire to overcome the limitations of traditional fixed-wing aircraft and to demonstrate the feasibility of rotorcraft. Cornu's pioneering efforts laid the groundwork for future developments in helicopter design and aviation.
