Ian, instead of always just asking the questions, how about you answer some? Tell us, do you ever have days when you make an error- something that on reflection you wouldn't do again if you could re-run the events and avoid? Do you feel anyone should have the latitude to rarely do things not quite as well as they would have liked without getting totally crucified for it? Have you ever made a professional mistake and found you had journalists sniffing around for a bit of blood, despite the fact that nobody got hurt and nothing was broken?
You might resolve your investigations into justification that you are furthering the cause of safety. Believe it or not, you are not really achieving anything. The safety system is acting now to investigate how and why this happened, and that is the reason that you are aware of the incident. Being an airline pilot is always a job of fine judgement of working as close to the safety line as possible within reason. Sometimes that line isn't readily visible, and occasional minor misjudgements occur. But overall, the safety system is working fine, and will be resolved without your input, but of course you want an exciting story of death on the high seas!
