June 23, 1931, Wiley Post and his navigator, Harold Gatty, took off in their single engine monoplane, the Willie Mae, on their attempt to beat the record for flying around the world. They succeeded by returning their starting point on July 1, after 8 days, 15 hours and 51 minutes. The previous speed record was set by the dirigible, Graf Zeppelin, in 1929 with a time of 21 days. Post and Gatty were the first to set the record in a fixed wing aircraft.
The People History also notes that Lena Horne recorded the "St. Louis Blues" on this date in 1941.
