In 1997 , SilkAir Flight 185 suddenly went into a high dive from its cruising altitude . The speed of the dive was so high that the aircraft began to break apart before it finally crashed near Palembang , Sumatra . After three years of investigation , the Indonesian authorities declared that the cause of the accident could not be determined . However , the US NTSB concluded that deliberate suicide by the captain was the only reasonable explanation
