Ok Frank, I fail to see how the demise of CYA has any sustainable relationship to an unfortunate error by a Metro crew that led to the sad LHR crash. How far back do you want to go? Air Cairns, Wings North, Sunbird Airlines, Air Qld, Bushies? If any one of them had not folded then there would have most likely been no Trans-Air Metro in the air that day either.
Clearly you are convinced there is a conspiracy. What are you going to do about it? Tapping away at PPrune is fine but fairly fruitless. Perhaps you could borrow Richards ute for another drive to Canberra?
If you are so well informed, have a read of the whistleblowers Legislation, get your evidence together and give it to em' between the eyes.
