      That's one hell of an article, thanks for posting it, ursus. It's not so much the on-the-fly software changes that are the problem, it's the change of purpose of MCAS from being a behind the scenes assistant to the pilots into a more general purpose stall prevention system. Couple into that Boeing's attitude to secrecy, even internally it seems such that one set of employees doesn't understand what some of their colleagues are doing, plus a thoroughly bad design implementation followed by a lack of proper testing, you end up with an aeroplane that's downright dangerous to fly when something as simple as a single sensor goes wrong. Also telling in the Boeing not understanding what they've created department is the disparity in the timescales between the predicted release of the software fix in the immediate aftermath of the Ethiopian Airlines tragedy and the reality.

        And another argument against agile software development. Fine in theory, and in some cases, but totally unsuitable for critical stuff like this.

          I do wonder if Boeing's increased focus on the military side of their business has been at least part of the reason things have gone so wrong with the 737 Max. The over-reliance on tech, secrecy and lack of co-oordination are all characteristic of defence procurement over here.

              That's assuming it will ever fly again.

              The FAA found more stuff wrong with the plane just recently. It was suggested on Dutch teletext that this latest problem requires not a computer software update, but a computer hardware change.

                Yeah, it's terrible news for Boeing, for sure. But I have few doubts that they'll all fly again. There's simply too much at stake for them to 'scrap' a full flying fleet of aircraft.

                  I'm flying Ethiopian Airlines to Hargeisa via Addis tomorrow morning.

                    Not on a 737 Max, though

                      No - they've gone back to the 737-800

                        "Photos have emerged of a repainted 737 Max in Ryanair colours outside Boeing’s manufacturing hub, with the name 737 Max replaced by 737-8200 on the nose"

                        Cheeky.

                          Damn good article that, and of what can happen when an engineering company ceases to be engineering-led. Nokia MP went down a not dissimilar route.
