On 31 October 2000, Boeing 747-400 being operated by Singapore Airlines on a scheduled passenger flight from Taipei, Taiwan to Los Angles unintentionally commenced take off on a partially closed runway in reduced (but not low) visibility instead of the correct runway without ATC being aware of the error. The subsequent collision with construction equipment and resultant severe post crash fire destroyed the aircraft killing 83 of the 170 occupants, seriously injuring 39 more and causing minor injuries to 32 others. All three flight crew survived.
