If we lost 75% of our upper ranks, apart from being more efficient and saving a great deal of cash, we wouldn't notice the difference.
This is a hoary old chestnut that often comes up. OK then, Piltdown Man, we've got (not counting specialist docs, dentists, padres and lawyers) just over 100 air rank positions. Forget 75%, how about you name just 10 posts that we could remove, and explain what we would do (or not) about the tasks that those 10 people do?
(BTW, I ain't in one of them!)
