So if Boeing is going to resume delivery from the stored frames, I suppose this gives them some buffer to restart the production line more gradually than the earlier plan, which was to just start shipping the new builds and feed in the stored frames independently.
I speculate Boeing bet on ready mass produced parts (pilot tubes and wires) and now some gizmo seems likely. If a mechanical part is required, return to service was delayed by months. Even a cheap custom gizmo takes time to qualify, then produce in numbers to get the grounded fleet going.
Boeing cannot be back at full production within 6 months. This reduces 2020 production by at least 250 (from 630, or <380 MAX produced in 2020).
So it depends on how you look at this The US economy just shrank by a minimum of $9 billion/year direct plus another bit of indirect in 2020.

One important reason why Boeing's share price is still up is that their customers have no place else to go. Both Boeing and Airbus have solid backlogs of orders.
Russia and China both have brand new planes to compete with the MAX and A320.

Now you seem to be ignoring what the initial testing prior to MCAS version 1 discovered, the stick fell forces during the required wind up turn did not meet specifications. We are now going back full circle to whether MCAS was a stall prevention system or required to ensure the MAX met the required FARS.

This is just wrong. Plenty of people killed themselves when they lost all their money. Boeing never set out to hurt anyone. A flawed system paired with inept pilots created a lethal combination. But plenty of financial firms were knowingly ripping off their clients and knew their life savings would be wiped out.

Incredible. If this is the end of MAX, would there be a sustainable way to reuse the already built parts? Like building a wind turbine tower out of the fuselages and use the wings as blades?

Where is the evidence that the MAX is such an unstable aircraft? I am going to make a wild guess that if it were so unstable, it would not be able to take off or even land by a human pilot. As to how far it goes - the essence of flying is to make constant adjustments. In the absence of automation or trim, the pilots will be making pitch and power adjustments for the entire duration of any flight.

No military customers exist for 300+ stored frames, besides, production of the military variant will continue.
Also, the same regulators who are reviewing the safety of the a/c also ensure that special requirements must be met for lines where military and civilian variants are produced.
Nope, they stay grounded until the FAA makes a decision.

If Boeing has completed every item to the FAA's requirements then I think an interesting legal battle may follow. Keeping an airplane that satisfies the FAA's requirements grounded just because they want a global RTS may very well be beyond the FAA's scope. That would be like the FDA forbidding a prescription drug that meets their standards from being sold because not every pharmacy wants to carry it.
I think the "the enemy of my enemy is my friend" principle applies here. That is the elephant in the room. There's a reason this thread generally goes quiet when the sun is shining directly over the Pacific Ocean. The change between the FAA being completely untrustworthy to now being unquestioned is noticeable.
Unquestioned FAA recertification is exactly the diametrically opposite to a global effort based on consensus finding. But consensus is an alien concept to many Americans so it seems. We already have two examples in this very thread.

If US declares MCAS as dual-use and imposes export controls under ITAR, BCA can sell non-MCAS MAXes with additional training to other countries. US Carriers can get MCAS option or additional training. This may be way out for current conundrum.
No delta training was Boeing's selling point, I don't think many airlines would be as adamant as WN to additional training.

That's not even the half of it. How about the Boeing employees? Anyone who thinks they will be immune has their head in the sand. And what about used prices and lease rates for A320s and 737NG's? What about the rates that maintenance contractors charge for overhauling old A320s and 737s, since that is all contracted out now (thank you Southwest)? As if the capacity even exists to ramp up. How about pilot hiring at major airlines? How many pilots won't get jobs because new airplanes won't be delivered? How many simulators won't be built? And what about airfares for next summer's travelers? "Capacity discipline" has just been forced on the airlines, yields and airfares should stay high. And what about the overall effect on the US economy of all of this unnecessary chaos? And what about media darling Southwest, that indirectly bears some responsibility? Gotta have that common pilot rating. How'd that work out?
I said months ago this was a full blown crisis. Many Boeing fanboys couldn't get their head out of the sand and see it. The responsible Boeing leaders should go to jail. This is a tragedy that began with the unnecessary deaths of almost 300 innocent people and continues to this very moment.

Every 737 fusalage is about 63 worker years in Witchita.
Every pair of engines is about 90 worker years. About 25 in Cleveland, about 25 at SAFRAN, the rest spread about (including EU, mostly USA)
Every plane has perhaps 25 jobs for a year at UTC.
British Aerospace has about 20 worker years per Aircraft (I don't know where).
Meggitt has perhaps 5 worker years per Aircraft.
Plus another 20 worker years st sub vendors I couldn't place.
Zodiac just took a hit.
As did Ricarro and every other seat vendor.
The above are my back of the envelope estimates. Does anyone have links to how many work on the 737?
The risk sharing partners will be hit hatd.
I understand the lives lost are valuable. But as an old salt, I know there will be mistakes of this magnitude. Mismanagement did make this happen.
But I also know that the riskiest part of a MAX flight today would be the walk from Airport parking to the terminal, which unfortunately a relative and his wife experienced this year that risk, they'll recover, but my relative isn't healed by any stretch.
As I had two friends in 2019 commit suicide due to job loss, that is my greater concern. I look at risk of death a the original system didn't meet requirements, but I'll know more people who die each from vaping, marijuana, car accidents, diabetes (self inflicted, not juvenile), drunk driving, opiates, and staring at their cell phones while crossing streets than aircraft accidents than air disasters.
This must be fixed. I believe the stand down is required.
I am one of many who didn't think production would be stopped. I see easy solutions. Don't get me wrong, if I had known how serial the risks were, I would veto as I often do at work. The difference is many customers know me. If I say don't do that or transfer me, everyone listens.
But there was a certifiable solution. Involving everyone (EASA, China, India) is politically required. But while they debate, jobs are lost.
I personally believe Boeing cannot restart until there is an agreed solution. Since about 62% of SAFRAN's new production (or I guess about 25% of their jobs) just received a stop order, plus British Aerospace, Meggitt, Japanese suppliers, even China (finishing centers) all just received a stop notice. I believe every certification authority was just assigned enough job losses that instead of discussing this for months at Boeing's cost, they just became serious.
Boeing just told the world they will sit and listen. I bet there will be the most productive meetings this week. I bet all compensation negotiation was just put on hold.
This is now serious.

Hindsight is always 20/20, but after the June fiasco, if Boeing had really slowed the train - say 20 per month - all and sundry would have been laser focused on getting the a/c repaired and dealt with the recriminations after.
Now the politicians are really going to get involved and it may get real messy, the new head of the FAA may not have the time to personally test fly the MAX.

What do you think the bad thing would be? That it gets to 12 degrees AOA and quickly pitches up another few degrees into a stall, or it doesn't meet the stick force regulations starting at 8 or 9 degrees? I could see why a lower trigger degree would not be trivial news.

If behavior without MCAS in the event of a sensor failure was a huge issue, they would have been working on a solution to add a 3rd sensor months ago. A 3rd sensor and processing to get an accurate AoA with a single sensor failure is the simplest solution if the plane can't fly without MCAS active.
