Air Vice Marshal Mike Lloyd, who is now retired but was in charge of RAF personnel at the time, was also criticised for his lack of knowledge of discrimination legislation, something the tribunal found "incredulous".
What I find "incredible" is the poor grasp of English of whoever wrote that. The tribunal can find his lack of knowledge incredible, or they can be incredulous about his lack of knowledge, but not the other way round
(Just edited to say that I've just noticed that
Waddo Plumber has already made this point, sorry about that)
By the way I wonder what Gp Capt Wendy would have made of the situation which existed when Mrs TTN was a QARANC nursing sister. As a female nurse with an SRN she was automatically granted a commission on entering the service (subject to passing officer training etc) whereas similarly qualified male nurses could only enter as NCOs (same rules applied in PMRAFNS). The court shoe was firmly on the other foot in those days!
