Yes he said that it was felt that all these planes operating outside of the control of the UK authority wasnt right. (not that he felt that personally but that this was an opinion that had been widely expressed at his meetings).
I can see their point. If loads of foreign cars were driving around the UK not taxed and insured here, we as citizens may complain. When you tie it in with the reasons why pilots choose this option then it seems unfair but seperately it seems quite sensible not to allow this operation. (not that I want them to stop it of course)
