From the article by Phelan (my bold):
One of the most disturbing aspects is that once again events have highlighted the apparent existence of an unacceptable culture permeating some elements of the Civil Aviation Safety Authority that not only allows the kind of misconduct we have detailed to continue, but either supports it or stolidly denies it exists. That kind of a culture cannot survive without the awareness of senior management. It is relevant that some of the names associated with these events he go back more than fifteen years.
Of further interest since this event first started, messrs Hood and Campbell have received promotions, as well as the head of internal legal, to Associate Dirctor.
