I’m being very careful to only focus on actual evidence. That includes there is no evidence the autopilot was ever re-engaged and the aircraft may not have flown on the centreline of airway N571. So it looks like it could have been a hypoxic ghost flight.
As for the cause, there is a ‘single point of failure’ that doesn’t need to be shoehorned too much to fit the evidence. So what is that evidence? L transponder stops, Satcom stops for about an hour, autopilot appears to be off, no Comms from pilots, hypoxic flight path(possible).
All the above failures would likely happen if an oxygen bottle were to rupture in the left side of the avionics bay.
But, of course, it has always been much easier to blame a nefarious pilot.
