For those asking about fuel loaded. It's entirely possible and indeed normal for the flights into and out off china to tanker fuel in because the fuel supply is not as good as outside of china and is much, much more expensive. So theoretically mh370 could have been full.
For what it's worth I'm not buying the flew on after fire incapacitated the crew, because a fire of that intensity would have brought the aircraft down in short order.
My credentials are ten years ground staff, but paid attention.
