"MH 653 was a scheduled domestic flight from Penang to Kuala Lumpur in Malaysia, operated by MAS. On the evening of 4 December 1977, the Boeing 737-200 aircraft flying the service crashed at Tanjung Kupang, Johor, in Malaysia. It was the first fatal air crash for Malaysia Airlines with all 93 passengers and 7 crew killed instantly. The flight was apparently hijacked as soon as it reached cruise altitude. The circumstances in which the hijacking and subsequent crash occurred remain unsolved."
