Pan Am Flight 812, operated by a Pan Am Boeing 707-321B registered N446PA and named Clipper Climax, was a scheduled international flight from Hong Kong to Los Angeles, California, with intermediate stops at Denpasar, Sydney, Nadi, and Honolulu. On April 22, 1974, the aircraft crashed into rough mountainous terrain while preparing for a runway 09 approach to Denpasar after a 4-hour 20-minute flight from Hong Kong. All 107 people on board perished. The location of the accident was about 42.5 nautical miles northwest of Ngurah Rai International Airport. Until the 1991 Jakarta Indonesian Air Force C-130 crash, it was the deadliest aviation accident to happen on Indonesian soil.
