Flash - Perhaps you should read again what I actually said and not make assumptions. The consensus is, I believe, that pilots may do what they wish within the law AND without endagering others. Do not try and emulate the military in a civilian circuit; as has been seen this can lead to tragedy and more sadly, tragedy for those on the receiving end of a quite dubious practice. I have no idea of your kind of flying or what you do to explore your "personal envelope" but what I do know is that if you "explore" in any way that presents an unnecessary or unknown danger to others then you have no business being in control of any aircraft. Perhaps we should start a thread listing those airfields that allow such actions as R&B and then the rest of us can avoid and see what happens when economics takes over.
