Closer view of Amelia Earhart in the Beech-Nut autogyro. Autogyros were sometimes referred to as gyroplanes, gyrocopters, or rotaplanes. The craft uses a rotor to develop lift and a propeller to provide thrust. Unlike a helicopter, the rotor is unpowered. While the propeller pulls the aircraft forward, air passing over the rotor creates lift.
