This thread has gone down a predicable path that I bet any O or SNCO from a Battle of Britian or a Bomber Offensive Sqn would recognise. However, back to now, we are becoming (in terms of aircrew at least) a 'pilot centric airforce' where the requirements for the Nav specelisation will become very soon, very niche.
I don't think anyone is suggesting that the WSO tasks that remain (even if/when P8 arrives) should become SNCO posts. The right people will be selected from the ranks of WSOps to become Os.
Now the only other issue is the claim that a non Nav WSO is not as broad an O as a Nav, that surely, just as with Navs is purely on the individuals experience and ability, any other attitude is now as relervent as Sight Reduction Tables.
