This topic certainly raises temperatures. Flash why are you unwilling to name where you carry out this military joining procedure? I shall continue to exercise my privileges as a pilot and not stay in my car. I merely wish to avoid any unnecessary dangers from pilots who want to do their own thing in a circuit pattern. You can of course go to your nearest military airfield and ask if you can play at being a FL pilot there. Equally if your own airfield has no pattern traffic you may do as you wish within the rules of the airfield. To say "they cannot disallow them" is something you may wish to clarify with the airfield management.
Lawyer - I think that my concerns are that we need to avoid getting the CAA involved. The fact that some pilots need to do this in a circuit with existing traffic is surely more likely to get the CAA involved than avoiding it. As I have said above - I believe pilots should be free to do what they want BUT not where it is LIKELY to endanger others. I am a most fervant supporter of GA and believe we all have a role to play in being seen to be responsible.
