Sure, an airport may have been there, but, in Boston at least, technology changes have made it so that if you are in the flight path, you have a much higher frequency of planes overhead. See the traffic from runway 33L at Logan airport as an example: https://www.universalhub.com/comment/559152#comment-559152 https://www.universalhub.com/comment/559152#comment-559152 Basically, flights used to have diverse paths, so you would hear a plane occasionally. And so would everyone else around. But now, if you are directly under the path, you will hear flights consistently every 90 seconds for hours on end. That is a major change, and a recent one at that.
