,,We remain confident in the fundamental safety of the 737 MAX.'' Am I irrational for not wanting to be on the first 1-2 years of flights on 737 MAX after it gets its software update?

I don't think the general public will be swayed. All it takes is a few Boeing PR campaigns and some time and people will forget.

It's now fairly obvious MCAS was at the root of those two crashes. But, did it save lives in other circumstances?

Meaning, was there ever a case where the nose went up so much, because of the bigger motors and their different location on the wings, that the activation of MCAS prevented a stall? I'm surprised no one seems to talk about this.

It's also surprising the MCAS was implemented at all, instead of an alarm. Yes, the point of MCAS is to make appear the MAX is the same plane as earlier models (when in fact it's not), but if pilots need to learn how to deal with MCAS malfunction, isn't it the same as learning to deal with unexpected stalling during take-off? The whole reasoning sounds kind of circular.

This is Boeing’s first volley as MCAS is now definitely and undeniably fatally flawed. I am fairly confident that by the time we are done with this, a system called MCAS never flies again. Even if it means the entire MAX is shelved.

That would be an astronomical loss, I just don't see that happening.

I think $3B in R&D, half of that is the engines, but more importantly, time to market trying to compete with Airbus.

They can reuse the engines. If the airframe can’t fly safely without MCAS (it’s getting a new type rating anyway at this point, right?) then I think perhaps it shouldn’t fly.

The only time it has been utilized that in the manner it was intended that I'm aware of is when it was exercised during it's test flights.

"We're taking a comprehensive, disciplined approach, and taking the time, to get the software update right." So what approach did they use the first time around?

I'm pretty sure this will end with retraining or the restoration of "pull up" method of the pilot overriding the feature (the later may require retraining anyway)

I guess you can't tell. You could see how often it operated but not know whether the pilots would have saved it. That said it's pretty unusual for professional pilots in an airliner to get into a stall situation.

Any PR pro worth their rate would have him and senior management very publicly flying only on 737 Max flights when they comeback online. Assurances alone are going to mean a very rocky road back for this plane.

They did that. Doesn't prove a thing.
