Harold Charles Gatty (5 January 1903 30 August 1957) was an Australian navigator and aviation pioneer. Charles Lindbergh called Gatty the "Prince of Navigators." In 1931, Gatty served as navigator, along with pilot Wiley Post, on the flight which set the record for aerial circumnavigation of the world, flying a distance of 15,747 miles (24,903 km) in a Lockheed Vega named the Winnie Mae, in 8 days, 15 hours and 51 minutes.

Wiley Hardeman Post (November 22, 1898 – August 15, 1935) was a famed American aviator during the interwar period and the first pilot to fly solo around the world. Also known for his work in high-altitude flying, Post helped develop one of the first pressure suits and discovered the jet stream. On August 15, 1935, Post and American humorist Will Rogers were killed when Post's aircraft crashed on takeoff from a lagoon near Point Barrow in the Territory of Alaska.

Post's Lockheed Vega aircraft, the Winnie Mae, was on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center from 2003 to 2011. It is now featured in the "Time and Navigation" gallery on the second floor of the National Air and Space Museum in Washington, D.C.
