I wear them. When I feel like it. in an old c172 doing flying with my mates from work. Guess that makes me a **** then? Luckily I am not one to be unduly concerned about others opinion on such matters. Aviation is filled with stuffy old geriatrics and is slowly dying out. If someone spends £10k to learn to fly as a PPL and wants to wear 4 gold bars and a white shirt who is ANYONE to say that they should not?
