Anyone reading it would have to compare with previous version, see that a word was supressed, would have to think "Humm, seems that it doesn't need to be continous anymore". And when the beast showed off slightly above ground, the last crew was expected to think "This shaking is active, it says I'm stalling, yes, surely this is related to the removal of the 'continous' from that checklist, let's do that!".

All threads were closed regarding "lack of new information, let's wait for substatial news". All threads hit a dead end with pages and pages of discussion on it was just necessary to "fly the aircraft", as if nothing else should be learned on why any crew would be doing something while heading to the ground that isn't trying to fly the aircraft...

If these details from newspapers aren't "news", I don't know what else would be. If all those details aren't enough to be considered on why the plane acted in unexpected ways for 3/3 crews, and just 1 one them could survive (and logged the problem with words clearly stating that they didn't consider to be MCAS problem... perhaps because MACS wa unknown until them)... if these details don't impact, at least, on how a crew should proced to recover from the problem... I don't know what else should be discussed.

Anyway, be it a big problem with many factors or be it just a matter that pilots should have done better, I don't think public is reliefed knowing that "you, travelling worldwide, do you know that certified pilots don't know how to deal with an easy problem that they just need to keep flying the plane?".
Well I have both the current NG & MAX QRH in front of me and both state “continuously” and that is at the root cause here.

I have flown classic, NG & MAX over the last 14 years and have never experienced a stab runaway other than in the sim and my expectation would be that it was running continuously, we are aware of the STS trimming the aircraft as it accelerates or decelerates, so I wouldn’t initially at least have given a second thought to the first inputs by the MCAS and with most being new on type would probably put any difference down to the type.
