ACA what a load of garbage. They can't even get simple facts correct for eg. "RAAF Blackhawk Helicopter pilot", wrong try Army, "GB" being a Qantas Skipper - wrong try Second Officer.
I'm still trying to follow Dicks argument here with regard to the two examples sited and Airservices. Since when did the intoduction of NAS involve increased Radar coverage. Dick try and be consistent with your arguments and may be you will have a bit more credibility.
