Why do these articles say so little about how Boeing fixed the problem? People are more likely to fly on these if they know what's different from the ones that crashed.

Patch notes: - bug fixes and general improvements

- reduced changes of uncontrollably flying into the ground at users' request

At least insofar as the US is concerned (and note many other regulating bodies are writing their own ADs, certifying the aircraft themselves), the FAA AD is https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgad.nsf..., where the actual changes operators are required to make start on page 45.

> Maybe they should have bit the bullet and fully redesigned the 737 That's EXACTLY what they didn't want to do. Airbus was able to do the 320Neo without a redesign. They essentially slapped new engines on it and made tiny adjustments. Boom, fuel savings. Boeing wanted to do the same. Their design didn't accommodate the bigger, more efficient engines they wanted. So they created a workaround. Redesigning essentially…

You're not wrong but with the crashes an actual redesign is needed.

The crashes wouldn't have happened with a better implementation of the same design.

Curious, I never want to fly in one of these. How can one achieve that in a realistic way? Let's say airline changes plane after I booked, then I wouldnt get a refund. Is there a solution to this?

It's usually stated when you browse flights, but obviously planes can be substituted before you fly. You can take your chances.

The best plan would be to avoid airlines that own the plane, but that will be impractical for most. Even then you might be re-routed onto another airline or third party plane.

> they didn't solve the physics problems created by the engine position The engine position, in itself, isn't terribly unusual; the 757 and 767 both have engines in similar forward positions on the wings and have a similar pitch up moment due to the engines at high angles of attack. So do a number of Airbus models. Designing flight controls to deal with this issue is not new and has been well tested. The particular i…

Does the 737 MAX now require pilot retraining? Or did they make some other sort of adjustment?

Yes it's required.

As with software, restarting from scratch can introduce many, many bugs. Boeing planes are super safe from millions of flighthours and the learnings and failures from before. The older aircraft annealed into a state of safety and reliability from known-ness. "fully redesigning," introduces a lot more risk.

>Boeing planes are super safe from millions of flighthours and the learnings and failures from before. Which you use to build off of.

in mission critical systems, build from scratches are rarely the case because any hiccups are disastrous.

It's why banks still run on mainframes despite trying (quite desperately) to get away from that.

Probably but now that the public is aware of a physical flaw covered up by a control mechanism the physical flaw needs to be fixed.

I'm not even clear what that fix boeing used to cover up this problem. The article didn't specify, that is a red flag.

I recently had the frivolous idea of creating a flight search engine for flights that DID NOT use the 737 Max. Any actual interest in this?

No, it is an irrational human fear. Hold one, humans are dumb so yes, it will be a money maker playing on that fear!

It's not an irrational fear at all. The plane by any measure is a serious kludge, even after these patches have been applied.

Think about the fact that you're flying what is essentially a management designed plane. No reasonable engineer would chose to build this plane.

Because they are journalists and have no idea how airplanes work or how engineering is done.

Well, I think it's just Boeing getting good PR, they even called journalists to the flight ... reminds me of this classic YC article.
