Wreckage of MH370 washing up on Reunion Island?

Depends where the fire begins. Could a slow burning fire take out the radio/comms systems without the crew noticing? Perhaps inmarsat stuff is located nearer the cockpit? Or could the aircraft remain flying with all flight controls at neutral, say if key avionics systems were lost? I have a feeling the fire would compromise the airframe before this would happen.

A fine plane might not have picked up the nickname cripple seven.

I just came back from vacation in Europe on a 777-200. Flew from London on Friday morning but had to turn back due to short circuits in (two separate) entertainment centers that caused smoke in the cabin. We dumped fuel and made an uneventful emergency landing. The airline paid for hotel, dinner, breakfast etc so not too bad. But the next morning, we boarded another 777-200 for another attempt just to find out that the co-pilot's instruments didn't match the pilot's. This wasn't detected until pre-flight check. The mechanics were called in and a bunch of things were replaced including the co-pilot's seat (apparently electronics built-in) before we could get on our way. Then we were told that the pilots' maximum wake/work time would be exceeded if we went all the way back to Los Angeles. This was "solved" by making an extra stop in Washington DC for crew change. I think the total trip took some 18 hours...
Not sure if we were double-unlucky but I'll remember Boing 777-200 and United Airlines for a while...

Double unlucky would be not finding the problem. Funny how stuff like that doesn't even rate a mention on the news. You'd think the reporters would be looking for every little incident and making a big deal out of it.

It does get mentioned on the aviation news; he was probably talking about this one: http://avherald.com/h?article=48a78266&opt=0
(MH370 is there too.)

Its a marvel of engineering that the 777 can stay together at those forces!
