Safe to say, if an intentional reroute (by crew or others on board) is indeed what happened, the best spot to do it would be approaching TOC, out in the middle of the ocean, as opposed to straight after take off whereby the response from authorities would be a lot quicker...
It struck me as odd, from the beginning, that a catastrophic event would happen right at the point of handover to another countrys ATC, where Comms were weak, and where radar coverage was nearing its limit. Not to say all the holes in the cheese lined up, it's definitely happened before, but .... if you planned to divert an aircraft, where else would you select?
