Having read all this from the outset, I'm becoming more persuaded by the concept of mass hypoxia ...
But what I can't quite grasp is:
- How (me not being a 777 driver) the last settings on the a/p don't sustain flight in that direction until fuel exhaustion. (= search offshore near Ho Chi Min city?)
- Why an initial track of 040-ish suddenly generates search activity on the west of the Malay peninsula. (= someone suspects something more than just that implied left turn at 'lost contact')
