Quite a disparaging statement I think. I am a "civvy" but have worked internationally with many ex military controllers, mainly great people but they all laugh about " inflated" military CVs, it happens all the time. As for the point of taking a military aircraft through UK airspace. That is what all controllers do day to day, mainly " civvy" controllers with a LOT more aircraft to handle. This is not management it is Air Traffic Control. Management is something completely different. Dealing with people, budgets, policy etc. Many controllers never want to enter that world.
As for not having a "civvy" ATC licence that, if true, is quite a shock. ALL previous ATC managers were fully qualified controllers and had to stand in when there were staff sickness problems.
