How did Lindbergh stay wake during his flight?

Charles Lindbergh stayed awake during his solo transatlantic flight in 1927 by taking short naps, no longer than 30 minutes at a time. He also consumed Sandwiches, coffee, and water to help him stay alert during the 33-hour journey from New York to Paris. Lindbergh's focus, determination, and physical conditioning also played a crucial role in keeping him awake during the historic flight.
