Creamy I agree with you, it goes without saying.
I think CASA and ATSB also agree with you - and calculate that they will be left alone accordingly.
There are three events that might change this:
1. An effective
PR/ industrial campaign by the GA industry, perhaps including strikes.
2. A major accident.
3. What I will call "chance" - I know of one chunk of a Commonwealth Department that got overhauled and employees removed after they got a little too arrogant in front of a bystander who just happened to be a very, very senior public servant.
