MPN11 - that thought crossed my mind. However, if that were to be the case then surely he'd be given the command as a substantive Gp. Capt. not acting?.
Just seems strange as the usual statement for Front Line Stations goes along the lines of..."Wg Cdr Bowden- Cable promoted to Gp. Capt. and assumes command of RAF Last of the Many in Octobuary 20XX."
There must be a few candidates within the plethora of Gp. Capts. at Air Command who are in line for a
Station Command - and despite the location - being "Boss" at any Station is a big tick towards the next rung on the hallowed ladder.
Could another reason be a possible return of an AOC (Scotland)? Thus having an Air Rank at said location would negate the need for a Gp Capt Staish.
