"Driving airlines away from the UK" is not necessarily a bad thing, and encouraging physical violence against those who argue against environmental damage is perhaps not the most measured response.
We have to balance the growth of our own aviation industry against the downside of such growth - and there are many, I'm sure, who would prefer to see airlines migrating to Schiphol and Frankfurt than see hundreds of acres of England disappear under tarmac and aviation fumes. I think most people would prefer our airports to be world-class in terms of their comfort, facilities and ease of use than purely in terms of number of flights, and the easiest way of achieving that - bearing in mind that none of our airports is easily expanded - is to reduce the number of flights.
If all EU nations take similar measures - as they probably will - then there will be no economic disadvantage to this country.
