Everywhere in the world where a significant city has built a second airport, traffic does not reduce from the primary zone, rather the volume of traffic increases significantly as the new zone provides a catylist for development.
TRU THAT!!!!!
But hey, we live in a major city with an international airport, an airport that has a curfew because of its position. We all have to make a few sacrifices when it comes to noise pollution (not sacrifices for some of us
) if we want to enjoy the service which is provided from the airport. And its really only in a 10 mile radius or so where the aircraft are still fairly low and at a high noise level.
