In such a scenario, firstly the communication with the home hub would have leaked and, secondly, in such an emergency situation with no other traffic around (4AM Local?) especially in what I believe were conditions of light winds at KUL, the aircraft would have come straight in over land for Runway 32 and not gone out into the Straits of Malacca?
But to deploy such enormous resources to the grid in the Malacca Straits, there must indeed be information which is not being shared.
