Aw leave the re-enactment folk alone. I saw them yestarday and commented to my other half that I didn't quite see the attraction, but a lot of people say that about my yak-habit and to be honest the more people we have taking any interest in any aspect of aviation the better.
I'm sure they're not meaning to offend anyone who actually wore the uniform or actually pretending to be real spitfire pilots.
I'm based at NW and I'd much rather people were out enthusiastically participating in or enjoying airfield activities and lending a buzz to the place than sat at home in apathy watching "a place in the sun/animal-diy-hospital" like the rest of this daft country while this ridiculous govt slowly bans everyone's hobbies.
Err... more power to 'em!
