Within the safety culture of most airlines, admitting a mistake publicly and taking the blame is a sign of strength..not weakness!
QF should be congratulated on their culture and humility and not dragged through the weekly beatings of PPrune on this one. I'm sure we can all learn a lot from this mistake and be better prepared to be even more careful with our paperwork and regulatory compliance.
No; I don't work for QF, but I still love the airline.
