KR,
I know of many similar experiences...additional to the fact that CONFIDENTIAL is an interesting word......
Especially when the reported organisation can quite easily work out who the reporter is/was due to the content (no matter how anonymised).
Fear of reporting and absence of reporting is as big a safety issue as the issues themselves!
A colleague of mine looked at “luck” in a slightly different way.
When something did not happen attributed to luck or good fortune he used to comment:
”P Rovidence was the controller that day” ...
Seems to describe the A320 / Jabiru incident well .... Given procedures and all safety nets apparently failed
