It is not so much the condo people living accross from the airport as it is the folks who happen to be living on a small corner of the island who would like nothing more than to see the airport converted to some kind of park. More to the point is there are other interested parties who would rather dispense with the airport and convert the land for further devellopment of condominiums.
Having lived in the area, I can attest to the fact that there is more pollution, be it air quality or noise that comes from vehicle traffic that runs along the freeway than from the airport.
