Parabellum, it's simpler than that: the option simply wasn't (isn't?) there. You couldn't join the AAC as an nco pilot. I might have. I'd like to hear from any loadies who would not rather be a pilot in any uniform.
Mark Terry went AAC from 33 in the 80s. Whatever happened to him?

Picture the Army Careers Tent camped outside the Cranwell (Biggin in my day) main gate on OASC day. Banner: "PASSED NCA? COME AND FLY ARMY AH". Takers, you reckon?
