I find it puzzling that airlines are still ordering this plane.
It's not just us, the customers, who should "vote with their feet", but the airlines, too. I would not buy from a vendor that is not able to have a QA process that makes sure all screws and bolts are in place, fastened and secured. Even if it would not be an airplane where this is critical for safety, even if it would just be a toaster, I would stop buying.
I would find it insulting as a customer to buy something for 50 Million USD to find out that the vendor was not willing to invest a little bit in QA. I understand that the 737 MAX is very cheap, but the damage to an airlines reputation, even if 90% of the customers do not care, should be priced in, which in the end makes it an expensive airplane.
Looking at the number of quality and design issue problems Boeing had during the last couple of years, combined with the press attention they are getting now, I think we can take it for granted that during the next couple of months more such issues will be found, including the "oops, that potentially could have crashed the airplane" category.
Also, I find it really insane that after all these issues the FAA still has not been reformed, properly staffed and funded. It really really should be clear by now that the system of Boeing doing the "certification" the FAA is supposed to be in charge of themselves.
And finally: It goes beyond my comprehension that someone would decide to build a version of the voice recorder specifically for the US that only stores 2 hours of voice, while the international version of the same plane stores 25. What kind of cost reduction per unit is that, $1 per airplane? Having two different models to "certify", produce and warehouse just to save a dollar or something per unit does not sound like any sane business decision.
Some people say that Boeing is that terrible because they cut corners to save costs everywhere. But to me it sounds like they even are bad at executing cost cutting...
