Charles Lindbergh and his wife, Anne Morrow Lindbergh, took this transmitter and other radio equipment on their 1931 flight to the Orient and 1933 survey flights across the North and South Atlantic. Because they were flying over vast stretches of unchartered territory in Canada, Alaska, and Siberia during their 1931 flight and Greenland, Africa, and Brazil during their 1933 flight, the Lindberghs relied on radio and navigation equipment to help them find their remote destinations.
