Evidence.
The GMA operates with the CAD's Condonance.
The GMA is a very good servant, he does what he is told and does it effectively. Most importantly he is feared by all pilots and when he speaks it is scripture. It is never challenged by any pilot or your AOA. The AOA fears him the most.
The CAD really has no say in this matter, they do what they are told by their boss which gets told by Swire. This is all done at the Hong Kong Club over a bottle of cognac. You are so naïve.
So go and collect your evidence, it makes for good recycling.
Your AOA is only good at collecting dust and they do what they are told.
Here's to my bonus.
