Malaysian Airline System Flight 653

Malaysian Airline System Flight 653 (MH653) was a scheduled domestic flight from Penang to Kuala Lumpur in Malaysia, operated by Malaysian Airline System (MAS). On the evening of 4 December 1977, the Boeing 737-200 aircraft flying the service crashed at Tanjung Kupang, Johor, Malaysia, while purportedly being diverted by hijackers to Singapore. It was the first fatal air crash for Malaysia Airlines^[2][3] (as the airline is now known), with all 93 passengers and 7 crew killed.^[4] The flight was apparently hijacked as soon as it reached cruise altitude. The circumstances in which the hijacking and subsequent crash occurred remain unsolved.
