Well the moonsaballon work and fly in the middle east with out uniform and you will end up at the wrong end of a AK47 happened to me in Jordon and never took them off out there after that.
This, and the story about my ex-colleague, who ended up in a Chinese jail, because the local cops didnīt believe that he was a crew member, because he was wearing civvies, is the sole reason.
If I would wear them (even white shirt, black trousers, black neck tie, as I have seen many British and Irish engineers do) e.g. on an ordinary line job in Germany, I'd be laughed out off the crew room.
