Interesting. Except is it really possible for a 777 that just had its entire avionics destroyed by a fire and a total loss of cabin pressure at 35k feet to maintain relatively level and straight flight? If the fire is really that catastrophic, I would reckon the plane would crash soon thereafter. It would also be unprecedented (as far as I know) to have the crew aware of a fire and unable to alert the ground (either because the comms were inoperative or the pilots were incapacitated). Also, another pilot is now claiming he established radio contact with 370 at 1:30, but that it was "mumbled" and brief. I guess the radio was working and there was a butt in the seat? I dunno. Who am I kidding, it's all circumstantial at this point. EDIT: I'm not sure if the Cairo incident is a good example of how quickly a fire can overcome a crew. They were on the ground with the jetway still connected, so it's quite a different situation.
