The first hull loss of a 747-400 occurred on November 4 , 1993 when China Airlines Flight 605 , flying from Taipei to Hong Kong 's Kai Tak Airport , touched down more than past the runway 's displaced threshold during 20-knot ( gusting to 38 knots ) crosswinds . Combined with the disengagement of auto brakes and retracted speed brakes , manual braking and thrust reversal were not enough to prevent the aircraft from sliding into Victoria Harbour . No one was seriously injured , but the aircraft was written off . The type 's second hull loss occurred on October 31 , 2000 , when Singapore Airlines Flight 006 , a 747-400 flying on a Singapore to Los Angeles route via Taipei , rammed into construction equipment while attempting to take off from a closed runway at Chiang Kai-shek International Airport . The aircraft caught fire and was destroyed , killing 79 passengers and four crew members . The cause was attributed to the flight crew navigating to the wrong runway
