Just to be clear, let's not pretend that excessive aircraft noise is caused by everyone on this tiny island flying all over the world (although many of us do), it's about Heathrow being the world's third busiest airport due to it being Europe's major hub. That is what the expansion plans are about: making more money and keeping business away from Schiphol and Frankfurt who are threatening to take some of that precious business away. The rights and wrongs of that are a whole other issue but this is not a simple case of people in London take flights and that's why a flight lands or takes off every 45 seconds at Heathrow.
