Page 2 of Lindbergh's October 14, 1935 letter to Donald A. Hall Sr. Lindbergh clarifies the history of the Daniel Guggenheim Foundation for the Promotion of Aeronautics, noting it completed its five-year charter, and reports that the St. Louis backers from his 1927 flight had invested in the Lambert Aircraft Corporation to construct a small low-wing commercial monoplane powered by a 90-horsepower Lambert engine.
