Thanks for the Lion Air FDR charts.
TTail It seems from the scale readings in the preceding Lion air flight, that they hit the cutout switches early on, before speed and nose down trim became excessive, and full manual control was possible.
In the fatal Lion air crash they did the opposite, relying on electric trim to repeatedly counter MCAS, until the captain relinquished control and the co-pilot added insufficient nose up trim.
The WSJ leaked Ethiopian crash details indicate a third scenario, unsuccessfully attempting manual trim after speed and stabiliser loading became excessive.

i am not sure if this was discussed earlier , was the stick shaker left active and the autopilot disengaged for the entire flight ?. Would this normally have warranted a more substantial maintenance action before the next flight.
That is the story, and why it was not reported is the million dollar question.
