Do you believe that the known flight path (turnaround at IGARI, flight over the Malasian penninsula while skirting the Thai border, the turn towards VAMPI with the 330+ nm flight up the Malacca Strait, the turn towards Banda Achi, and then the turn at POVUS (all the while staying out of the Indonesian FIS) which brought the flight to a heading of almost 180 degrees) could have occurred as a result of anything other than human choice? If so, you are going against the consensus of opinion on the matter; thus, you really should explain your belief in detail.
The credibility of this flight path, which conveniently skirts everyone's airspace until the path is clear is not established.
Various military and government sources have claimed radar detections that have been combined to put this track together, but there has been no independent review that all could reference. The plane is basically anywhere from the last 'Good night' till the first Intelsat fix.
