I believe the next CAS did not "look down his nose" for a Sqn Ldr job in a Station based HQ and JHC! Have a look at his bio.
I agree that selection of jobs at SO1 level make a lot of difference, but at SO2 level, where it is a little less competitive, it isn't as critical. I'ts just that those with burning ambitions tend to gravitate to MB, PJHQ and PSO jobs - if they do a good job then they normally go at least 1-2 ranks up, if not, they stagnate with the rest of us at Wg Cdr max.
Anyway, back to Flt Lt and Sqn Ldr stuff...
