I wouldn't be surprised if Ben Morgan has already been "captured" by CASA, especially if the rumor of a CASA overture to let RAAOz run private GA has any truth. That move would leave AOPA gasping for air in my opinion.
As I asked before; who is drawing up the agenda for the summit? Who is taking minutes? Who is running the steering committee for the summit and who is on it?
Hearing nothing, my expectation is that negotiations have been "taken private". I therefore expect nothing further on Pprune and/or to be told to pull my head in.
To paraphrase Sir Humphrey Appleby; never hold a summit unless you already have determined the outcome. The Public service are masters at this game.
I am hoping that somewhere there is an AOPA steering committee with maybe a few QC's with aviation interests advising them.
