Most people living near airports moved in after the airport was built. They, like, knew the airport was there when they bought or rented the place! And today’s planes are far quieter than they were decades ago. Airport noise is less of a thing than it used to be.
So I don’t have a lot of sympathy when people complain and try to restrict flights in and out of airports, complaining about the noise. But it turns out that not many people actually complain.
