TTN you must remember that I retired from the Hairy Arm Corps a third of a century ago and I can't claim to be au fait with todays service! That said, the majority of pilots in my time were SNCOs or W/Os. I am also old enough to remember a rating pilot (with bell bottomed trousers and a kiss-me-quick hat) of the FAA and of course the RAF in the old days had plenty of non-officer aircrew.
