One resident says he's never seen as much anger and shock as he has about the new Dublin Airport runway.
The North Runway was opened last week, after years of planning and construction delays.
But Mick O'Rourke of the St Margaret's The Ward Residents Association said planes aren't sticking to the routes.
He told Lunchtime Live he actually supports the new infrastructure.
"I'm 70-years-old... and I've lived in this whole area all my life: I have never seen as much anger and shock in the community.
"I welcome the opening of the runway - it's good for the country, it's good for Fingal.
"But the situation has turned... that everybody was told that planes are going to go in on a particular flight path.
"As part of that process, DAA was involved in providing an insulation scheme into some 200 residences in the area."

He said the insulation would follow the flight path, going out from the end of each runway.
"However when it opened on Thursday morning there, it was like pigeons being let out for a race.
"There was planes going out and they were going left, they were going right.
"As far as we're concerned.... we're saying they're actually illegal.
"They were not part of any restrictions put in on the planning process.
"The planning process were that the flight would go out in certain directions.
"If this was going to be changed, then they need to immediately go in and the contours that they're using to insulate homes must be reassessed".
A public meeting is being held by local residents on Thursday.
