Part of me wonders if the plug could be designed such that it's obvious when the bolts are missing. Would this have happened if it were impossible to assemble without them, or if it were easy to verify their presence?

Maybe it doesn't matter if a better design is possible - if adequate procedures exist and weren't followed, and oversight fails to catch instances of that, then anything could go wrong.

It sounds like Boeing is doing a design enhancement. I found this article [1] that describes features for the bolts as:

> The fix also includes adding lanyards atop the door-plug bolts to “permanently secure the bolts to the plug” and “provide a visual indication”, says Crookshanks. “They’ll hang there and be visible to a mechanic that had taken the bolts out.”
