Sadly,
"I don't care how they do it in the USA "
seems to be the prevalent attitude amongst those who have expropriated control of the airspace over the UK.
Any informed observer has to accept that the environment is different here. But if the powers that be promote the idea that there is nothing to be learnt from elsewhere, then nothing will be learnt.
The lesson that should be taught is that airspace is a common resource, It belongs to everyone, not just BA et al. AOPA in the US do the political lobbying to this effect, very effectively it would seem.
As ever, when Government is involved, money talks.
