@
Sanji Himura no one doubts the capability to recover the files (drive type depending, of course), it's the 'red herring' that they represent in terms of the story (as @
BobK said). The files could be related to anything, and even if they
are from flight sim (and if the story's even true) then there's still nothing suspicious about it.
From what I understand regarding a theory of fire and heading set until fuel stops, the ACARS system would report any irregularities in the operation of the aircraft...it would report the use of fire suppression systems, shut down of other electronics, and ultimately the engines running out of fuel. Data to that effect has not been reported, Right?
It
could transmit some of that data, part of the confusion is what it was transmitting. It only sends short packets at intervals of many minutes so isn't a live telemetry feed in that sense.
You're right overall though, the plane should have been sending
some data to somebody. If it was running on autopilot then it had 'operating system authority', it had hydraulic power, it had some central power.
The authorities' data seems to be as specific as how the new course data was entered (keystrokes on center console), that isn't part of ACARS and is a strange thing to know, if true. I'd expect in an emergency that if they were using the autopilot they'd dial settings in on the console at the top of the main dash. Typing into the FMC is much more relaxed and premeditated.
That's what makes the mystery so bizarre - there is no one explanation that adequately fits the known facts.
This remains the problem. Somehow the plane was in an emergency state (presumably) but couldn't communicate (incredible over any period of time). The pilots may have been overcome by either incident or human force, and the route settings may have just been temporary while the pilots controlled the emergency (switching between aviate and navigate, never reaching communicate). I find it inconceivable that some message wouldn't have been relayed if the pilots thought they might have to ditch.
I remember that on some 747s the senior cabin crew had access to a radio so that they could exchange instructions with the ground if necessary, I don't know if that was restricted to a model/airline or if its available on the 777.
All those passengers, all those phones, not a single message. That doesn't make any sense, that leads me to think that the plane was subdued or destroyed. Or that it never took off, the transponder was on a different aircraft*.
