Narrative:All Nippon flight 58 departed Sapporo (CTS) for a domestic flight to Tokyo-Haneda (HND) and climbed to an altitude of FL280. While cruising at this altitude, it approached an area where a Japan Air Self Defense Force student and his instructor were flying in their North American F-86F fighters. The trainee was not watching out for traffic when the 727 approached. The instructor ordered him to break away from the 727. It was too late. He banked to the left but the leading edge of the right wing of his F-86F (92-7932) struck the left horizontal stabilizer of the ANA plane. The fighter's right wing broke off, causing the plane to crash out of control, but the pilot ejected safely. Damage to the stabilizer caused a loss of control of the B727.
