I don’t care much one way or the other about the airport. Expand or contract, makes no difference to me.
HOWEVER, that airport and the surrounding business park was there long before the houses were. As far as I’m concerned, if there was any poor planning involved it was on the part of the people who bought in those areas without first deciding whether they could live in proximity to an airport.
Not only should their complaints be roundfiled, they should reimburse the city and the airport authority for costs associated with this frivolous opposition. Grow up and stop whining.
