AOTW, I see you still refuse to address the conclusions of the Forsyth Review.
I think, since the conclusions of the Forsyth review have been studiously ignored by CASA, we can safely conclude that CASA is now a bad actor and therefore does not require or warrant "nice professional gentlemanly treatment" they have received this from the industry for 15+ years anymore.
To put that another way; professional reasoned argument has been tried on CASA with little result. We can therefore conclude that "the problem" of aviation in Australia is CASA itself.
The fact that you and I have not had a bad experience with CASA is not relevant since plenty of other people have had such negative experience of CASA they were prepared to go to the time and trouble to tell a Senate Committee about it.
