The Focke-Wulf Fw 61 holds the distinction of being the world's first fully functional helicopter. Developed by German aviation engineer Heinrich Focke and pilot Gerd Achgelis in the 1930s, the Fw 61 showcased groundbreaking technology and demonstrated the feasibility of vertical flight. Featuring dual rotors mounted on top of the aircraft, the Fw 61 offered enhanced stability and maneuverability. This pioneering helicopter achieved numerous milestones, including the first free flight of a helicopter in 1936 and the establishment of several world records for altitude and speed. The Fw 61's success paved the way for future helicopter designs and laid the foundation for modern rotorcraft. With its innovative engineering and historical significance, the Focke-Wulf Fw 61 remains an iconic symbol of human ingenuity in the realm of aviation.
