In 1933, the famous eyepatch-wearing Wiley Post touched down in New York after completing the first around-the-world solo flight in seven days, 18 hours, and 49 minutes. This being his second famous flight, Post had completed an around-the-world trip just two years earlier with navigator Harold Gatty onboard to keep him on course and alert. So how was he able to complete a similar flight with no partner on board? The answer, of course, was autopilot, which kept him flying in the right direction while resting. This was not the first time autopilot was employed, nor would it be the last, as autopilot has now become a common feature on aircraft that uses many of the same basic principles as were utilized on Post’s flight more than a century ago.
