@Pace:
Why on earth would a hijacker wanting to route somewhere want to bother loading a route or flying waypoints?
One reason: to avoid try and avoid detection until closer to intended destination. Heading selector seems an easier way, though.
I also wonder how deep the seas are in the areas being searched?
The area ~ 2000 miles west from Australia? Thousands of feet deep, most of it looked to be past the 1000 fathom curve when I consulted an old atlas last night.
This pic may help.
This has a bit more detail.
