Tartare...thanks. Its an illusion.
As someone else already mentioned the satellite data is filtered for characteristics, otherwise there would be a flood of data from lightning, gas flares, fireworks etc. But I believe, based on an article years ago, that the data stream can be retroactively inspected without the filters.
WRT to tank rupture/ignition. It takes a lot to get jet fuel to ignite...atomisation, lots of heat etc.. Cruise speed at FL350 would present a much smaller possibility of ignition than speeds, pressures and temperatures typical in landing accidents.
