One was slaving away on the 4th Floor of MoD Main Building when the WSO/Op "RAF" brevet was being staffed. Originally and (IMHO) incredibly, the original draft had the Crown only on WSO (ie commssioned) brevets!
Until we pointed out that whern we had non-commissioned pilots, their wings also had crowns ..
And of course I write as a fully paid up, commissioned member of the TWMR!
And I'm sure I saw Simon Bryant with a WSO brevet?
