Beancounters in Air Services and the airlines don’t want to do anything other than put band-aides over the ugly, running sore. ATSB and CASA are either unwilling or unable to say anything critical about the ugly, running sore. It’s not ‘corruption’, in the sense that no one’s getting bags of cash to look the other way (so far as I can tell), but it’s ‘corruption’ in the sense that every government body responsible for ‘safety’ is either unwilling or unable to call it for what it is: An ugly running sore.t
It's actually noone in the responsible organisation(s) wants to be
accountable for the decision. So what they do is make no decision and then pile a bunch of reports in front of them as a wall of protection saying that " we came to the conclusion there was no evidence that a tower was necessary and here are all the reports justifying our position"
That will be their defense in a Royal Commission if there is 200 fatalities in a mid air.
