Desc: World's Smallest Airport: Directed by Matt DeGennaro. With Bob Brussack, Grady Thrasher. In 1945, when Word War II ended, three brothers returned home eager to resume their civilian lives. Starting from scratch, in a few weeks they acquired airplanes, took over a rural airport and created The Thrasher Brothers Aerial Circus. For five years, the brothers performed astonishing acts - doing unlikely things with unlikely aircraft - feats that have never been exceeded to this day. This is their story.
