You change wings.
I remember buying OG/black wings/name badge combined for CS95. [Aunt Liz awarded me wings and no pillock desk jockey was going to deprive ME of wearing my hard-earned badge!] DIOT agreed and had a set made for himself, after he wrote a blistering letter up the chain about waste of time, money, etc, tinkering for the sake of it. But then, Bobbie Robson was a REAL leader and did not suffer fools gladly.
Is there not a flying version of CS95? Properly anti-fodded [buttons held on with tape, etc] and fire-proofed? I seem to remember the truckies wearing them a while back....
