Having read this thread, and being an ex PM, when I was around the the Matron in Chief/Director Nursing Services (MiC/DNS) was a one star rank, this was dropped when we contracted in size after Options for Change. As one of the early commissioned male PMs, we were looked upon as being 'invaders' into the cosy PMRAFNS as previously all male nurse who were commissioned were in the Med tech branch. In fact the PMRAFNS of all three services had the first male MiC/DNS in Bob Williams who was Matron at Wroughton and then eventually made Air Commodore.
Fiona McGlynn is now a Squadron Leader.
Looks like the RAF medical hierarchy have dropped a big clanger in this case, would any aircrew suffer, and we have heard of the many exploits of Air Commodore Joan Hopkins in the Fighter Control Branch, by the same bar to promotion, I think not. This maybe a case of Doctors trying to limit nurses progression and not having a nurse as their 'boss'.
