Dick, I showed your response to my colleague. He just laughed. There is no point in debating with someone who doesn't listen.
He speculated that the reason you are having another tilt at ramming ausNAS down the industry's throat is; "you know the FAA is moving towards a different model- 'in or out'? It sounds like your guy there has realised that pretty soon he wont have an argument because the US model will have changed." Have I called your bluff?
