As a Waddington local who attended the show in flying suit I think I can offer a few concillitory comments. Firstly, local orders re the wearing of badges strictly follows 2 Gp orders and is enforced.
SRO's stated that hats were not to be worn on the airfield side. The AAC guys were obviously not aware of this.
Certainly, I experienced and talked to some Cranwell and UAS cadets who's behaviour was inappropiate and immature. Perhaps that's a sign of the times.
Both days were hot and sunny and sun glasses were essential. Until the RAF issues Raybans or Oakleys, people have no choice but to wear their own.
It's also worth remembering that an awful lot of spotters like to dress up for the day. I saw a few who had the full regalia including a couple with rank stripes.
I thought it was a great show and on the whole the RAF presented itself very positively and effectively.
