Investigation Summary
The aircraft, a Boeing 747-121 named Clipper Ocean Rover, was cruising at 36,000 feet approximately 225 kilometers northwest of Hawaii when the device detonated. The explosion occurred under seat 47K, which was occupied by 16 year old Toru Ozawa. The blast created a hole in the cabin floor and caused significant damage to the ceiling and overhead racks. The flight crew, led by Captain James E. O'Halloran III, maintained control of the aircraft and initiated an emergency descent. The investigation linked the bombing to the 15 May Organization, a Palestinian splinter group. The perpetrator, Mohammed Rashed, had reportedly placed the bomb under the seat during a previous leg of the aircraft's journey and exited the plane before the Tokyo-Honolulu segment.
Final Conclusions
The incident was a deliberate act of terrorism. The aircraft was repaired and returned to service, eventually being scrapped in the 1990s. The primary suspect, Mohammed Rashed, was eventually captured in 1988 and faced multiple trials in Greece and the United States. Another suspect, Husayn Muhammad al-Umari, remains on the FBI Most Wanted Terrorists list.
