I have yet to see a coordinated, coherent group of concerned aviators do anything other than tap out their righteous anger on a computer.
Exactly what I was getting at.
I was watching the news some time back, I forget exactly when, but there was a story about truck drivers protesting something about their industry.
What they all did was get in their trucks and they all drove down to Parliament house in Canberra. They didn't do anything illegal, but it certainly stopped traffic for miles around, got them some good coverage and furthered their cause. They banded together as one and created change for their industry with a tiny amount of civil disobedience.
Surely a mass fly-in at Canberra would create a similar amount of disturbance around the airport, maybe cause significant delays to politicians flights, get some media exposure etc.
If nothing else, it would be nice to the GA parking area at Canberra full again!
