There appears to be the thought Glen's handling of his matter is not causing concern and turmoil in CASA. I seriously doubt that is the case.
The Iron Ring has closed around the CASA staff involved as CASA will never admit wrong or mistake. Regardless of cost, morals, Regulations or The Act, CASA will progressively take all players out of the game, the "reticent" operator, the operators senior and management staff and the CASA staff involved. That is exactly what occurred in my case, in a previous life, previous century.
In my case, it ended up with return of the AOC in a very remote place and the comment from a DAS that "The matter should have been handled differently". It was a long time later that I found out "the matter" was probably related to an unrelated event a decade earlier.
