I would have thought it is also important for the Qantas management and Board to know the truth
You'd think so, Dick, but sadly they don't seem too interested in the truth when it's unpalatable.
Except when it can be spun into something positive -e.g. "These staples in this wiring loom don't show that our maintenance practices are bad. They actually show how good our maintenance practices are. After all, we found the staples, didn't we?"
