There is no time to consult manuals, when a plane is in a vertical dive, due to stall. Reaction time must be spontaneous. It may be that some change has been made to the pitot tube, which therefore gives a wrong airspeed indication, leading to stall. This is yet to be determined, however my question would be what are the redundacy systems to validate airspeed? Both Lion Air and Ethiopian airways crashes show major similarities, with no time for response and recovery, as still at quite a low height.
