Mach,
I don't disagree, especially with the training and skill part. I understand that the SO 'outranks' the CSM. However, the Pilot/Flying Officer, outranks a SGT/WOFF from the day they start, but that doesn't mean the loadmaster SGT/WOFF deserves less then Pilot/Flying Officer pay.
One could argue that instructors deserve more then SO wages, because without the instructors, the SO would never of gain a licence, learnt the skill to be able to hold a pilots licence.
