It would be interesting to see this non existent data which will be measuring engine inlet time stamped temperatures and pressures (hence altitude profile etc) or even knowing the time when Rolls Royce contacted Malaysian Airlines of inform them that there Jets engines have suddenly failed or that there was loss of the engine performance data stream communications.
