but expecting to fly through military training airspace and then file an airprox/airmiss is in my view unacceptable, coupled with poor airmanship
Sorry to disappoint you but such airspace does not exist in the area to which you refer. The civilian operator in question has as much right to operate in that airspace as you do. It is encumbent on ALL users of class G to give due regard to other users of that airspace.
As an aside, if you take the attitude that "well they should not be there so stuff em" and fly close to those aircraft, rather than giving them a wide berth, the TCAS and Airprox reports will increase, which in turn will strengthen the Airline Operator's argument for more Controlled Airspace. This will mean that you will have to find somewhere else to conduct your GCI!
