I would be pretty upset if all of a sudden my house was under the flight path of a new airport (and the associated economic consequences) but I always find it surprising how annoyed people get that put a house near an airport and then complain about it, where one of my parents lives there is a small but fairly busy private airport that has been there close to a hundred years, so almost no one that lives by it now can…
You understand a new airport generating complaints based on loss of value.
Have you considered what successfully getting an airport shut down might do for the nearby property owners?
It's not uncommon for people to try to (often successfully) tell other people what they can and cannot do with their own land, simply for the benefit of the one trying.
