{{More citations needed section|date=May 2024}}
After the record-setting flight, Post wanted to open his own aeronautical school, but could not raise enough financial support because of doubts many had about his rural background and limited formal education. Motivated by his detractors, he decided to attempt a solo flight around the world and to break his previous speed record. Over the next year, he improved his aircraft by installing an [[autopilot]] device and a [[radio direction finder]], that were in their final stages of development by the [[Sperry Corporation|Sperry Gyroscope Company]] and the [[United States Army]].{{citation needed|date=June 2020}}

In 1933, Post repeated his flight around the world, this time using the auto-pilot and [[compass]] in place of his navigator and becoming the first to accomplish the feat alone. He departed from [[Floyd Bennett Field]] and continued on to Berlin where repairs were attempted to his autopilot, stopped at [[Kaliningrad Devau Airport|Königsberg]] to replace some forgotten maps,{{citation needed|date=June 2020}} Moscow for more repairs to his autopilot, Novosibirsk, Irkutsk for final repairs to the autopilot,{{citation needed|date=June 2020}} [[Skovorodino, Amur Oblast|Rukhlovo]], Khabarovsk, [[Flat, Alaska|Flat]] where his propeller had to be replaced, Fairbanks, Edmonton, and back to Floyd Bennett Field.  Fifty thousand people greeted him on his return on July 22 after 7&nbsp;days, 18 hours, 49 minutes.<ref>[https://web.archive.org/web/20160328182451/http://firstflight.org/wiley-h-post/ "Wiley H.
