Why not just promote people who know what they are doing into positions managing people doing what they themselves once did?
If I understand the question correctly, the answer is a repetition of what has gone before. Skill in the job is absolutely no guarantee of an ability to manage, and nowhere is that more true than in air traffic control, where management jobs are often latched on to gratefully as an escape from the workface, especially by those whose ability in the field was marginal.
And no, I don't believe the Airservices board should necessarily have an ex-controller on it. The last board demonstrated the folly of that proposition.
