Just looking at DrKevs post.
I too lived in Portmarnock for most of my life. Noise was not an issue and we are talking about the days of BAC 1-11's and 737-200's etc, etc. When the last Ryanair 200 completed it's final flight, the noise problems, of which Portmarnock residents have ranted on about for so long, disappeared.
I can't blame the Portmarnock people for giving out though. Now that the Velvet Strand has more or less washed away, there's not much else to do!!
