Dick,
What's the saturation of movements V controllers (in various types of airspace) in Australia V the US?
Did you catch the Fin Review article yesterday on the inequity of money raised via "user pays" vs actual cost to provide given service? ASA and CASA featured prominently.
Finally, if ASA hired you to report on their current systems, you'd get all the access you need. Perhaps you should put a proposal to them?
I'll get me coat.....
