I disagree.
How many mid-airs have we had in the UK in any given period you could name? (As I said in the programme, sooner or later one will happen. But there is more than one way of ensuring that day is as far away as possible.)
I can't think of any. I can think of a great many near misses. Sadly, the military are responsible for far more than their fair share, but that's life.
Next, compare, say the number of CFITs in the UK, or any other accident cause.
My thesis is that our airspace can be made safe for all, that we can have a system of airspace that serves all those who have the right to be there - transit traffic, heavy jets, light regional stuff, business users, military, training traffic, microlights, gliders, ag sprayers, skydivers - the lot.
At the moment all we have is a "system" that has grown up piecemeal, developed by tinkering with it each time it became too unwieldy and useless.
