How can we balance environmental concerns with aviation needs?
It’s mostly landing/takeoff records. Big airports have takeoff and landing fees and would keep records such as this for accounting and legal reasons. Being a major airport like LAX means it’s probably mostly private/commercial jets, but also plenty of small time hobbyist aviators are probably wrapped up in this, and would be the only victim here ( general aviation pilots tend to use smaller, local airports but still on occasion hit the big ones).
