and the inability to wear the RAF Approved Jacket when flying,
As such a thing never existed when I was in (pre 77), as I read through this thread I assumed this was, in fact, a flying jacket? If the above quote is accurate, however, what is it for? For FJ jocks to stand around in at air shows looking steely-eyed perhaps? Not that I can believe they'd ever wish to do that, nor need a leather jacket to achieve the effect.
