In 1942, with a letter of authorization from Henry L. Stimson, U.S. Secretary of War, Rickenbacker visited England on an official war mission and made ground-breaking recommendations for better war operations. He inspected troops, operations, and equipment, serving in a publicity role to increase support from civilians and soldiers. Later, he worked with both the Royal Air Force and the United States Army Air Forces on bombing strategy, including work with air chief marshal Sir Arthur Harris and general Carl Andrew Spaatz.Lewis, W.
