I'm worried about boarding any Boeing aircraft at this point. The revelations paint a picture of an engineering culture deep into the normalization of deviance [1].
The planes they built before the current era of management should be ok. I've heard the 777 has the best safety record of any plane flying, but it was engineered before the current management.
Yes and that's the point. As a lay person it's not my business to determine which Boeing aircraft are safe and which aren't. Boeing's conduct has dealt tremendous damage to their reputation for safety and this casts a shadow over the entire fleet. They have to do a lot of work to rebuild that reputation and restore the public trust.
As a lowly passenger I don't get to choose which plane I am assigned to, also the airline seems to change it on a whim.
At this stage I'd be unhappy to be on a modern Boeing but I don't know what I could do about it, except cross my fingers and hope I won't be the next victim. I don't know what rights I'd have to claim a refund or demand a different model plane.
