The Wright brothers and Glenn Curtiss had early flying exhibition teams, with solo flyers like Lincoln Beachey and Didier Masson also popular before World War I, but barnstorming did not become a formal phenomenon until the 1920s. The first barnstormer, taught to fly by Curtiss in 1909, was one Charles Foster Willard, who is also credited as the first to be shot down in an airplane when an annoyed farmer broke his propeller firing a squirrel gun.[4]
