Answer:
Hallucinations, sleep deprivation and fog
Step-by-step explanation:
One of the main challenges for any pilot to experience is bad weather. During Charles Lindbergh's flight he experienced a lot of fog over the Atlantic Ocean from New York to Paris.
Another great problem was that he had trouble staying awake. The flight time was recorded to be a total of 33 hours and 30 minutes, however he reportedly was awake for much more than that, for a total of approximately 55 hours.
