>No re-training of pilots: Pilots were not aware of new ways in which the plane might take command away from them, and were left in the dark with only seconds to react to a deadly situation
Both the Lion Air and Ethiopian Air flights recovered from the initial MCAS. The mistake was assuming that pilots could reliably recover from a runaway trim situation. That might have been true when that was a more common failure and when pilots had more experience flying with manual trim.
Agree with you, though as a small correction it now appears (according to Ethiopian preliminary report) they made it to 7k altitude AGL, not 1k AGL. Still not so much to work with when you're above the plane's max airspeed and trimmed all the way down.
