Clyde Edward Pangborn, nicknamed "Upside-Down Pangborn", was an American aviator and barnstormer who performed aerial stunts in the 1920s for the Gates Flying Circus. He was its half-owner, chief pilot and operating manager, working in partnership with Ivan R. Gates. In 1931, Pangborn and co-pilot Hugh Herndon Jr. flew their plane, Miss Veedol, on the first non-stop flight across the Pacific Ocean.

Barnstorming was a form of entertainment in which stunt pilots performed tricks individually or in groups that were called flying circuses. Devised to "impress people with the skill of pilots and the sturdiness of planes," it became popular in the United States during the Roaring Twenties.
