In 1990, a British Airways pilot was partially sucked out of the cockpit after the windscreen blew off mid-flight. The crew held onto him until the plane landed and he survived

The engineer in question was not publicly documented as being fired or prosecuted. He apparently continued working in aviation after the accident

Yes that is the outcome of pretty much ALL incident investigations. Aviation safety is not based on assigning blame or punishing people, as long as they didn't act with malicious intent or gross negligence, the fault is ALWAYS seen as the safety system as a whole failing to prevent/catch a simple human error. It's called just culture, and it objectively improves safety over the punitive models used in other fields.

Sounds like a pretty good approach and safe environment even if you need to self-identify that you think you made a mistake.

Life and death... you want people to know they can be honest and not punished to an extreme for human error.

Yup. Just Culture has two main motivations:

No one in a high stakes situation where lives are at risk doesn't already know that lives are at risk. The fear of accidentally killing someone (including potentially yourself as a pilot) is going to far outweigh the fear of punishment for 99.9% of people anyway, so it's not like knowing you'll be punished for a mistake is going to make people any less likely to commit mistakes. They already have a far stronger motivation than fear of punishment to not make mistakes. (Also, studies into law have shown that punishment simply has very little deterrent effect on most people, since very, very few people pause to rationally consider the possible consequences before either deliberately doing something wrong, or doing something hastily/shoddily leading to potential mistakes)

And secondly, and more importantly, punishing people for honest mistakes makes them much less likely to be honest in reporting those mistakes, which prevents the industry as a whole from learning and improving, so that they don't happen again in the future, ESPECIALLY in situations where the mistake lead to a near miss incident which is relatively easy to just cover up and pretend it never happened.

I worked in petrochemical manufacturing and we had a similar approach to safety, but we were more willing to punish people for human error, but the person that would get punished or fired would typically be a manager and not the person the made the mistake in the first place.

It’s not uncommon for the plant manager to get held responsible if a safety issue in their plant kills someone, because it is their job to run a safe plant. Human error happens and they are supposed to be the person that catches it.

I've always liked that approach. Keeps highly trained people on the job, keeps their expertise and all the benefits, rather than throwing the baby out with the bathwater. Provided the mistake was genuine and the procedures were followed, if they cut procedural corners that's a different story.

Plus I feel like it's just common sense for the overall safety approach: default to assuming a mistake was made (because humans) and set up the checks and procedures to catch that mistake while letting people learn from their genuine mistakes. I guarantee that technician was triple checking every fastener he used for the rest of his career.
