> Not a single engineer raised issues with the engineering of the aircraft. Not a single engineer wrote a blistering memo calling out its failing or quit in protest.

I don't think this is true. There was an HN thread some time ago on an article describing how one senior production manager, who was an engineer by background and had previously worked at Boeing as an engineer, looked at the design specs, talked to people he knew in engineering, realized there were problems coming, and did exactly what you describe: wrote a blistering memo, found it wasn't going to get listened to, and quit in protest.

I would appreciate the citation, not doubting but would love to read it since I have not seen anything like it in the public domain.

Unfortunately I haven't been able to find it. If I do I'll post a link here.
