There is, I believe, an issue here that relates to expense borne by the public purse. Flying suits are expensive items and the cost of replacement falls on the public purse. Unless officers uniform allowance has changed, replacement falls on the individual. So why do aircrew not on flying duties get clothed for free by the taxpayer?
Having said that, I was privvy to a remark by an American widow to her late husband's commanding officer as she left the memorial service following his demise in a flying accident: " My husband's flying suit was good enough for him to die in but not to wear in your goddam o-club!"
An emotive subject indeed.
