Post 2 is the radar range of the Air Traffic and military radar in the area.
YPCC is the Cocos Islands that have an 8,000 foot runway. They only receive an average of 1 flight per day and their radar was likely turned off for FL370.
The pilot would have known that and could have steered for the radar gap between Diego Garcia and Leartmonth and headed for the southern India Ocean.
This is the only explanation that well fits the flight time to 0811. The northern corridor would have put FL370 well over land and they would have been spotted by now.
So, I withdraw my theory of the pilot choosing to attack India, running out of fuel and ditching in the Bay of Bengal. FL370 had much more fuel and flight time than thought.
