- 1:07 - ACARS last transmission (thru VHF) which apparently includes notation of a WP change having been entered into system since last scheduled report at 12:37
- 1:11 - Boeing would have received attempted message to their AHM (thru Satellite)
- 1:19 - 'Alright, Good Night' at handover (supposedly by co-pilot)
- 1:22 - Transmitter goes off
A question. Could PF have made a course change at 1:07 in such a way that PM would either not have noticed or not have questioned? (For example, saying it was a course correction, or waiting until PM was distracted by making a cabin announcement, etc.)
If so, I could envision the PM finishing his radio duties ("Good night.") and then having the PF send him onto the cabin on some sort of errand (or even just saying that there was a pretty girl back in the 10th row that had been making eyes at him, and he should go talk to her.)
Then PF locks the cockpit door and does whatever he wants...
