The residents of Forrestfield may object to having a rwy well within a km of their homes
I will be surprised if they didn't. Every single issue, minority interest group will come out of the woodwork with action groups, websites, rallies, t shirts and hats but when the dust settles, after they all realise that it is FEDERAL land and a third runway has been planned for at least forty years it will go ahead. The same reason that the brickworks could not be stopped by state regulators. The same reason that Jandakot has the spud shed and Harvey Norman wanted to open there before trading laws were changed. Federal land and federal jurisdiction with only a nod to state concerns.
People in Forrestfield also have the marshalling yards between them and the airport.
Anyway, the ANEP contours would show little "side" noise surely?
