When Spitfire, Soarin' and Misty go to judge the 'Best Young Flier' competition, Spitfire only expected to be bored to tears watching amateur fliers peruse their casual hobby; but things take an unexpected turn when two ponies fly onstage for the last performance. For the Wonderbolts, unexpected is usually a very, very bad thing.
