List of experimental aircraft
This is a list of experimental aircraft. Most aircraft are marked as experimental when they are first designed, so this list will focus on notable vehicles that never went into production and experimental variations of vehicles that were produced. This list will focus primarily on those aircraft that carried the "X" series designation or carried the "X" series designation as a prefix to a prototype, preproduction, or test aircraft.
