I think it is an issue that divides people neatly into two camps and I know which one I'm in!
Thing is though, you can indeed see aircraft in authentic colours and markings in lots of places. But on that basis one could paint-up any of these aircraft in silly colours and it wouldn't really matter much, whereas flying an aircraft uses money and fatigue hours that could be used when the aircraft actually looks like it did when it was in military service. Like I said before, if one doesn't care about authenticity then one may as well fly any old plane, surely?
I agree G-HUNT did look great and it was a real thrill when it first appeared. But the thrill soon wore off when more Hunters re-appeared, and most wearing their proper military paint schemes. Suddenly, a red Hunter just seemed like a bit less interesting
