When Charles Lindbergh was asked by Pan American Airlines to conduct survey flights, there was no doubt in his mind who would be his copilot: his wife Anne Morrow Lindbergh. In 1931 and 1933, Charles and Anne set off to determine where air routes and airports might be located. Anne learned Morse code and how to operate radios for the flight. She became so talented at this work that she won awards for distance flights and radio operation.
Today, when you fly to Europe you’re still using some of the same routes that Charles and Anne surveyed.
