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.
Every critical step should be as "idiot-proof" as possible, until better idiots are created who hammer structural parts into position to meet management-mandated arbitrary deadlines.
Hammering structural parts which don't want to go is hard work and if your workers have union protection you can bet they'll say "No". So what you need are strong union protections so that they feel able to say "No" when asked to do unreasonable things. Does that mean they're going to be a little harder to manage? Maybe, but mostly it means "Rule by fear" doesn't work and leadership might need to learn to inspire not threaten.
Union protections help in one place you're already familiar with. If your pilot says "No, I don't like those clouds at all" and won't fly, the airline can't fire them for that. That's their judgement, if you fire pilots who you feel aren't risking passengers necks to make the line go up you're not going to have any pilots at all.
Historically it helped for traffic control, but that's OK our old friend, Cowboy Actor and Friend of the Working Billionaire, Ronald Reagan smashed that, so now traffic control has the shocking poor working conditions Corporate America loves.
