that bit of footage. it may be almost out but i would guess any fuel in the aircraft has either leaked out, been burnt or been suppressed by the fire suppressant foam that they use. the plastics may be under control and they will look closely at other sources of fire that will need to be addressed. another element of this is there are a lot of electrical systems and wiring on an aircraft, so they could also cause challenges in managing the whole situation of the fire. it is not only fuel and fabrication materials of the aircraft itself. thank you very much indeed, john strickland, for your time and your analysis. stay with us here on bbc news as we continue our live coverage of the plane on fire at tokyo airport. plenty more also for you on our website any time but we are monitoring that breaking story
