Perhaps as pilots we have that compulsion to know every little detail of the timeline and sequence of events during this tragic crash. That's not a bad thing, but perhaps we might have to accept that much of these details will remain conjecture amongst us. The important things will come out from this investigation. Did any aircraft system or component fail to operate in the 'normal' manner? If it did, did the display and warning systems alert the pilot in a timely manner? If they did was there evidence that his reaction to the events could be described as reasonable given training/experience etc.
Sadly, we must realise that many interested parties will want to prove it wasn't their fault, the AAIB report says the engines could turn, though the media says they failed, so the engine manufacturer will want to refute that strongly and perhaps point the problem towards the fuel supply. The Fuel system manufacturer will want to say it all worked perfectly and that the transfer pumps should have been on and would have kept the engines turning if they had been. Though there is recent evidence of less than satisfactory fuel system reliability with the 135 fleet (after the fact). The operator will want to make it clear the pilot was properly trained and qualified, fit for duty etc. That very quickly ends up with someone having to try to prove the pilots actions and I don't know who's batting for him.
