The only issue I have here with this theory is the amount of time the plane was flying whilst a full scale fire raged through the plane (assuming all the Passengers and crew were dead from smoke inhalation). Wouldn't a fire burning that long (5 or 6 hours) have destroyed the intergrity of the plane, the fuel pumps, none of the avionics could still be working ie Autopilot, surely the plane would have crashed long before it could fly on for 5 or 6 hours ??
