Flight jacket? Sounds American to me, we always referred to flying jackets, etc, in the RAF (or has that changed?)
I thought that the Armed Forces Act 2006 made the wearing of any military decoration, badge, wound stripe or emblem without authority a criminal offence?
I think you are correct, However back in the 70s I remember reading an officers' confidential order to the effect that officers were to desist from approaching and hassling civilians who were wearing RAF greatcoats, etc, as these had been sold through RAF surplus supplies, and the purchasers were fully entitled to wear them. Might have been different if they wear wearing wings, medal ribbons etc
