With the cut-out, MET commands don't register, so MCAS is not reset and does not make further inputs.
So are you suggesting that the only reason both aircraft became uncontrollable and crashed is DIRECTLY BECAUSE the pilots attempted to counter MCAS with trim inputs, albeit insufficient?
Further, that if both accident crew simply ignored the initial MACS input and continued to fly the aircraft with the resulting out of trim state that no further MCAS action would have occurred, and they'd have survived?
It seems a highly ironic and depressing thought that the 2 subject flights only became uncontrollable because the pilots tried to fight the effects of MCAS with manual trim.
