I live in Chiswick just off the A4. HACAN annoys the hell out of me, they are simply a job creation scheme for professional nimbys who have discovered a soft target in Heathrow(the big..the multinational...the profitmaking evil empire etc etc).
Now try banning boy racers on motorbikes, trucks, and close the M4 after 11pm.
After all, sometimes it keeps me awake......
Cities make noise, its a trade off for vitality, economic power and the ability to get a loaf of bread at 4 in the morning if you need to.
As the previous respondent suggested- if you dont like it-move to Cornwall.
Here's my vote for an extra runway and a circular high speed rail link between Heathrow, Gatwick and Stansted.
I havent noticed the value of houses in Hounslow being diminished in the slightest by the prospect of a 3rd runway, but then again I'm not planning to move.
