So, let me get this straight.
A WSOp down the back of a Nimrod can't then become a WSO?
Where do, what were, AEOs come from then?
An Eng on the flight deck of a Herc can't apply for a commission?
Where does his boss come from?
Same question for loadies.
Are you seriously saying that what were NCO Aircrew cannot now apply for commissions within their trade/branch?
