It sounds like right after the first crash they knew what was going on but didn't bother to ground the fleet.

This stands out to me, and I have severely lost trust in Boeing and the FAA.

This plane should have not allowed to fly after the first crash, and Boeing knows this!

What a disaster - I will refuse to fly in any if these MAX planes going forward. I will not step my foot onboard.

He could put his safety where his mouth is and vow to only fly on the MAX for the next two years. That would be a much stronger vote of confidence than whatever words his PR firm came up with.

That's a terrible show of confidence. What are the chances that the next plane to have an accident is carrying the CEO? What is the average expected punishment to the CEO for getting it wrong? It's probably less risk than BASE jumping. I would rather there be guaranteed liability: have the execs set up a legal system to refund the entire order book and voluntarily plead guilty to federal charges in the event of anoth…

I haven't seen any mention yet specifically, are they being held liable for the deaths and forced into some financial penalties or has this case been relegated to the right-wing "The free market will adjust and discourage consumers" sort of liability?

The integrity of engineering excellence should never be sacrificed for profit and/or conveniency in places where it involves human lives. Realistically and pragmatically speaking, you only ever get to have just one single shot at establishing and maintaining that kind of life/death level of trust. Fuck it up, and you're gone- quite literally, mind you. This is some Challenger O-ring type of shitshow. Accidents are on…

>The integrity of engineering excellence should never be sacrificed for profit and/or conveniency in places where it involves human lives. That's just unrealistic. Unless you want plane and car rides to cost as much as a trip to space, after all, since everything would need to be engineered to that level of quality.

I continue to be fascinated with consumers who assume the role of shareholder in times of crisis, even against their own interests.

> We remain confident in the fundamental safety of the 737 MAX He just finished several paragraphs about how the plane and it's software was not safe ("erroneous activation of the MCAS function"), and then arrives at this conclusion? If my car erroneously responds to the pressure on the gas pedal it's not safe.

If he says anything other than that, odds of the 737 MAX being scrapped entirely (from customer and air passenger pressure) goes up. Saving face to save the share price.

Maybe it shouldn't be, but your comment is surprisingly cynical to me.

I don't believe share price is at the front of his mind, nor any of the engineers working at Boeing. I, for one, work for much more than a paycheck; I think it's reasonable to think they do too.

You could argue that it was at the front of their minds before these accidents, but IMO that conclusion only stands in confirmation of some bias against large corporations (which apparently is pretty common!)

What is more likely? That Boeing is genuinely sorry for their enormous process failures (that others on HN have documented in great detail) to catch these product deficiencies earlier in the process, failures that have killed hundreds of people? Or the catastrophic financial losses they will suffer in the event they are forced to scrap the MAX?

I'm cynical because of Occam's razor, not because I want to be. I'd very much prefer not to be cynical, to tell you the truth.

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.

you just rename it I guess. Like, Fly-by-wire is not new, airbus has been flying this way for 30 years, and had some bad early accidents because of it. The name of the system doesnt matter very much, so I fail to understand how the name would ground the airplane forever

That’s not what I meant. I mean a background system pushing the nose down without any active control input from the pilot while autopilot is off.

Versus Airbus which moderates pilot input to keep within the flight envelope, but I don’t think it steers without inputs when autopilot is off?

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. Ye…

> It's now fairly obvious MCAS was at the root of those two crashes. But, did it save lives in other circumstances? Let's say Boeing ships a new airliner, where in 1/1,000 flights, the wings fall off for no reason. Would you be asking the question of: "But did the wings save lives in other circumstances?" Of bloody course, they did. Doesn't mean that they should have ever shipped an aircraft, where the wings fall off…

I'm not trying to defend Boeing, I'm trying to understand if MCAS is actually needed in real life.

Reading the other comments it seems the answer is yes.

That said, it's unclear that a Max with MCAS is dangerous: the danger comes from pilots not being aware of it / trained for it. Which, again, doesn't disculp Boeing in any way.

I see this playing out in a couple of possible ways. One is that it ends up like the DC-10. Public confidence is lost, even though the problem is fixed. The aircraft end up going into freighter service. The other is that they make a convincing case that the problem is resolved. I don't know if that's possible given today's default hate for big corporations, we'll see. They've done it before with the 737 and the rudde…

In all fairness this plane is only a danger to its crew (and to regular commuters). Even without the software fix, the probability that you get into a crash in one of the few times in a year when you make a leg in this plane is still infinitesimal. For the crew that spends the whole year in there, different story.

,,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?

Am I the only one who would have no trouble flying on a 737 MAX?

Thanks for paying for testing!

Here's one example on why they might have thought it was necessary: https://en.wikipedia.org/wiki/Air_France_Flight_447
