The concluding page of Charles A. Lindbergh's December 5, 1927 letter to Donald A. Hall Sr. Lindbergh emphasizes the durability of the engine by noting that even the piston rings did not require replacement, reports that he has had two night-landing parachute flares installed directly behind the cockpit, mentions plans for night flights, and closes with warm personal regards to his Chief Engineer.
