The J-11B jets, which duplicated the Su-27 jets' superior maneuverability, made defensive maneuvers by turning left to right. When Major Choi Young-ho gave chase, the Chinese pilot reduced his speed to make an overshot and turn perform Caesar's maneuver. Then, the Chinese pilot continued to make reverse maneuvers in an attempt to tail Major Choi Young-ho. As a response, Major Choi Young-ho responded with a tumbling maneuver that defied standard aerodynamic movements. The jet leaned forward, turned a 180, and then turned upside down in front of the J-11B jet.
