Page 2 of Charles A. Lindbergh's March 6, 1940 letter to Donald A. Hall Sr. Lindbergh expresses his gratitude that Hall documented the complete technical and aerodynamic record of the Spirit of St. Louis immediately after the flight while the data was fresh in his mind. He encloses a copied excerpt of Page 4 from Hall's report containing the official roster of personnel responsible for the construction of the aircraft, suggesting Hall's associates would be interested in preserving this definitive organizational record.
