There is a helipad on the Yarra near my apartment. And it's starting to piss me off. When I first moved into the neighbourhood, there wasn't much chopper activity at all and I barely noticed the noise. Indeed, the only concern I had was to make sure my apartment insurance covered my property for aircraft impact.
Now the choppers are coming and going at a much higher frequency and the noise is terrible. It looks like I'm not the only one getting annoyed by the increased activity. Grrr.
