Minneapolis-born aviator Charles "Speed" Holman is killed during an air show in Omaha. A pioneer of aviation, his best-known aerial stunt was looping, and he had won the US air speed trials in 1930. At his funeral, four 109th Air Squadron planes flew in the first recorded Missing Man formation, with a vacant spot reserved in Holman's memory. Holman Field at the St. Paul Downtown Airport is named in his honor.
