Lindbergh's heroic flight thrilled people throughout the world. He was honored with awards, celebrations, and parades. President Calvin Coolidge gave Lindbergh the Congressional Medal of Honor and the Distinguished Flying Cross.
In 1927, Lindbergh published We, a book about his transatlantic flight. The title referred to Lindbergh and his plane. Lindbergh flew throughout the United States to encourage air-mindedness on behalf of the Daniel Guggenheim Fund for the Promotion of Aeronautics. Lindbergh learned about the pioneer rocket research of Robert H. Goddard, a Clark University physics professor. Lindbergh persuaded the Guggenheim family to support Goddard's experiments, which later led to the development of missiles, satellites, and space travel. Lindbergh also worked for several airlines as a technical adviser.
