Bombing

.

The flight crew consisted of veteran Captain Eduardo "Ed" Reyes, First Officer Jaime Herrera, and Systems Engineer Dexter Comendador.

Yousef assembled a bomb in the lavatory and put it in the lifejacket pocket under Seat 26K on the right-hand side of the fuselage, setting the timer to detonate the explosives four hours later. Domestic flight attendant Maria Delacruz noticed that Yousef kept switching seats during the course of the Manila to Cebu flight. Yousef and 25 other passengers left the plane at Cebu. 256 passengers and a different cabin crew boarded in Cebu. Many of them consisted of Japanese people; some of them were coworkers traveling as part of a tour group. Airport congestion delayed the departure of Flight 434 from Cebu for 38 minutes. All of the passengers boarded by 8:30 a.m.; the bomb had been planted around two hours earlier. PAL 434 cleared for takeoff at 8:48 a.m.

Two hours before arrival at Tokyo, the bomb exploded at 11:43 a.m. while Flight 434 cruised on autopilot above Minami Daito Island, which is located near Okinawa Island

 and is 260 miles (420 km) southwest of Tokyo.

The explosion ripped the body of 24-year old , a Japanese businessman occupying the seat, in half. He was an industrial sewing machine maker returning from a trip to Cebu. The lower half of his body fell into the cargo hold. Ten passengers sitting in the seats in front of and behind Ikegami were also injured; one needed urgent medical care. The bomb tore out a two square foot (0.2 m2) portion of the cabin floor, revealing the cargo hold underneath, but the fuselage of the plane stayed intact.

Masaharu Mochizuki, a passenger on the flight, recalled that injured passengers initially tried to move away from the blast site, but cabin crew told passengers to remain where they were until an assessment of the situation could be made. Fernando Bayot, a flight attendant covering the forward part of the aircraft, moved an injured passenger away from the bomb site. Bayot then saw Ikegami and tried to pull him out of the hole but soon realized that most of Ikegami's body below the waist was either damaged or missing entirely. Ikegami died minutes later; Bayot called another flight attendant over to pretend to minister to Ikegami's needs with a blanket and oxygen mask in order to prevent additional panic, then reported the extent of the passenger injuries to the cockpit.

Immediately after the explosion, the aircraft banked hard to the right, but the autopilot quickly corrected the bank. After the blast Reyes asked Comendador to survey the blast site to check for damage. Reyes placed the Mayday

. The Japanese air traffic controller experienced difficulty in trying to understand Reyes's request, so an American air traffic controller from a United States military base on Okinawa took over and processed Reyes's landing. The autopilot stopped responding to Reyes's commands and flew past Okinawa. Reyes said in an interview for the Canadian TV series Mayday

that when he disengaged the autopilot, he feared that the aircraft would bank right again and the crew would lose control of the aircraft; however, because of the pressing need to land quickly to attend to the injured and inspect the plane for additional damage, Reyes instructed Herrera to take hold of his own control stick, and then Reyes deactivated the autopilot. The aircraft did not bank after the disengagement of the autopilot, but neither would it respond to steering inputs from either controller due to control cable damage caused by the bomb's explosive energy which made the plane's skin expand rapidly. The crew struggled to use the ailerons, which could allow the aircraft to turn, but still were unable to change the plane's direction. Finally, the flight crew disengaged auto-throttles and resorted to steering via throttle control, reminiscent of United Airlines Flight 232

.

By using the throttles to steer the plane, reducing air speed to both control the radius of turns and to allow the plane to descend, and dumping fuel to lessen the strain on the landing gear, the captain landed the damaged Boeing 747

-283B at Naha Airport at 12:45 p.m., one hour after the bomb exploded. The aircraft's other 272 passengers and 20 crew members survived.

. However, on the SAS Version model of the 747, used in this flight, seat 26K was two seats forward of the tank. If the bomb exploded in a horizontal manner it would have punctured the aircraft skin, causing explosive decompression

. Instead, the explosion occurred in a vertical manner running front-to-back on the plane; Ikegami's body took the brunt of the force, people immediately in front and behind were injured, and the sudden vertical expansion of the cabin severed steel cables controlling the 747's rudder and elevator located in the aircraft ceiling. The bomb also severed the copilot's control cable for the right aileron.

Aftermath
