I think CV is an excellent ambassador for the Air Cadets. I don't thing many (any?) within the organisation would complain about the manner in which she is promoting the ACO and aviation.
I do slightly agree about

PS. Just Google Gp Capt Carol Vorderman and look at some of the excellent picture of her with air cadets. Another (in)-famous female aviator wouldn't have subscribed to such natural images diverting attention away from her ego.
