Rules for wings on CS95 were changed in March of this year. The line in the Dress Regs AP was even written in bold and underlined as if to stress the point. Long story short; wings may be worn on CS95 unless operationally inappropriate. No doubt this change came after CAS was back briefed on PPrune comments
I believe that CASWO is 'selling' the issue of leather flying jackets to all RAF Servicemen/woman (to wear with blues) in a morale boosting exercise. Sounds like one of the budgets is a bit overfull.
