Kudos to you, Roly old mate, for continuing to endure all this wiggy woke nonsense! I hope that you're still able to take to the WBY and 'turn your bum to the sun' regularly to escape such bolleaux?
Back when the Specialist Aircrew scheme was first under consideration, people were consulted about whether they should have distinguishing rank insignia etc. When responses such as secret handshakes were suggested, the idea was dropped. Happy faces at the prospect of increased flying pay and no promotion exams, plus many years of flying tours were sufficient indication of status!
