We have 'em protesting at EMA at the mo over possible expansion plans, but the old adage "expand or die" comes to mind.
Having lived 1 mile from LHR and 1/2 mile from EMA, I can honestly say that I haven't experienced any excessive noise pollution, but I was wearing industrial strength earplugs at night !
.
I hope that they all have viable alternative plans to add to the argument, the "long-haired, leftie,lesbian commie scum...etc etc etc..!"
