I agree gundog01, williamtown has been a defence airfield since February 1941 and has since agreed to share its area with civilian aircraft. I also know williamtown serves as a training grounds for not only its fast jet boys and girls but its new ATC staff also, and you can often sense the uncertancy over the radio while they're watched by there trainer. But I think we sould be lucky that we can still fly into willy since 9/11, and in fact any millitary airspace as a matter of fact. I have flown into willy hundreds of times and very rarely have we been held. Of course some 'unusual' clearances appear but take it or leave it....my two cents anyway
