At 11:43 am, about an hour and a half from Tokyo, the bomb exploded while Flight 434 cruised on autopilot above the Japanese island of Minami Daitō (near Okinawa Island and approximately 260 miles (420 km) southwest of Tokyo). The explosion ripped the body of 24-year-old , a Japanese businessman occupying the seat where the bomb was placed, in half. Ten passengers sitting in the seats in front of and behind Ikegami were also injured while one needed urgent medical care. The explosion tore out a two square-foot (0.2 m2) portion of the cabin floor into the cargo hold but leaving the fuselage of the plane intact. The airplane was spared from a deadly fiery explosion as the seat where the bomb was planted, 26K, was two rows away from the central fuel tank. The rapid expansion of energy from the bomb caused the plane to expand vertically slightly, damaging cables to the steering and aileron controls. The bomb's orientation caused the energy to be mostly absorbed by Ikegami; he was killed but the other passengers and the plane were not catastrophically damaged.
