How accurate were those left, right, left turns and the vectors on the images a few hundred thread pages back? The right turn after crossing the peninsula appears headed back to Phuket which may have been the nearest airport. Might suggest one of the FD crew momentarily recovered from the initial/onging event or hypoxia and was trying to get the airplane on the ground. Also, if the initial event took out the ARINC 429 buss, that might explain the loss of ACARS, Transponder, and all communications.
