Malaysia Airlines Flight 653 (MH653), a Boeing 737-2H6 aircraft registered as 9M-MBD (delivered September 1972 as 9M-AQO), crashed at Tanjung Kupang, Johor, in Malaysia on the evening of 4 December 1977.
It was the first and deadliest fatal accident 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.
Currently, Malaysia Airlines uses flight 653 as a flight from Penang to Singapore which operates daily, departs 13:15 and arrives at 14:35. The opposite is flight 652 as a flight from Singapore to Penang which operates daily, departs 11:05 and arrives at 12:25.
At approximately 1954 hours, while at an altitude of 4,000 feet over Batu Arang and descending toward Subang's Runway 33, captain G.K. Ganjoor reported an "unidentified hijacker" onboard to Subang Tower. The tower immediately notified the authorities, who made emergency preparations at the airport.
