To those who fly/work on 777s... How feasible is this?
1. Rapid decompression caused by exploding crew oxygen tank, or decompression aggravated by fault in cockpit oxygen tank/line;
2. Pilots don masks but there is no oxygen flowing and they aren't aware;
3. Pilots initiate descent and course reversal but mess up the interaction with the MCP and command FL295 instead of FL100 or similar;
4. Pilots become incapacitated within 30-60 seconds (time of useful consciousness as per source -

5. Incapacitated pilots inadvertently turn transponder to off or standby;
6. Pilots go unconscious as plane flies towards Andaman Islands/Bay of Bengal;
7. If spoilers had been deployed, A/T commands sufficient thrust to maintain (or attempt to maintain) MCP altitude and override effect of spoiler deployment;
8. Aircraft at near-max thrust runs out of fuel much more quickly than aircraft at cruise thrust, falls into the Bay of Bengal between Andamans and India/Sri Lanka.
What technical factors support or invalidate the above chain of events?
Thanks for all the input...
