It comes up a lot, but it’s an incredibly important story that bares repeating often. Especially with similar issues like the 737-MAX occurring pretty recently.

Oh for sure, and the purpose of those links is not to imply that it's too often. Reposts are fine on HN if a story hasn't had a big discussion after a year or so (https://news.ycombinator.com/newsfaq.html). I just list them because people often like to look at the past threads. That's what "For the curious" means :)

Yeah aparently we have to constantly relearn that software hotfixes are not an acceptible substitute for hardware interlocks and good overal design practices when lives are at stake.

As a long time subscriber to the Risks mailing list, I would have to note the extensive discussion of this incident:
