Anne Morrow Lindbergh served as co-pilot and radio operator during two trans-global flights with her husband Charles in 1931 and 1933. She used this rear cockpit control stick to fly their Lockheed Sirius airplane while Charles took breaks to sleep. When not piloting the plane, she removed the control stick so she could more easily perform her radio duties.Prior to the 1931 flight, Anne worked hard to learn aviation skills and Morse code in order to earn her pilot license and radio operator's license. She thus felt slightly insulted when women reporters seemed more interested in her clothes or where she packed the lunch boxes on the airplane. Charles, however, always recognized her importance to their success and called her "the crew," a term that made her proud.
