A "Barrel Roll" is an aerial maneuver where an aircraft rotates 360 degrees around its longitudinal axis while following a helical path. This move is often used in aerobatics and can be performed by various types of aircraft, including military jets and stunt planes. The maneuver is characterized by its smooth, rolling motion, which can be visually impressive. In video gaming, particularly in the Star Fox series, the term "Barrel Roll" became popularized as a defensive move that players can use to evade enemy attacks. The phrase "Do a barrel roll!" is famously associated with Peppy Hare, a character in the game, encouraging players to perform this maneuver during gameplay.
