The term 'Barnstormer Feat' refers to a type of aviation performance that was popular in the 1920s. An AVIATOR (7 letters) is a person who pilots an aircraft, an AIRMAN (6 letters) is a military or commercial pilot, a FLIER (5 letters) is someone who flies an aircraft, a HANGAR (6 letters) is a large building used to store aircraft, and a LOOP (4 letters) is an aerial maneuver in which an aircraft flies in a circular path. The Barnstormer Feat was a combination of these elements, where an AVIATOR would fly an aircraft in a series of loops and other stunts, often in front of a large crowd.
