Aircraft noise can change after an airport is built. From the article: > The multibillion-dollar program is changing the way air traffic is managed, moving it from radar to satellite navigation. Proponents say it makes the air traffic system more efficient because it allows planes to fly more direct routes to their destinations. > But the shift has angered residents, who live in neighborhoods that are below the new flight paths. Residents in Northwest Washington sued the FAA over the changes but lost in court. A suit filed by the state of Maryland is pending. > McCann was one of those affected. He lived in La Jolla for more than a decade and, other than the occasional stray plane, had not had problems with noise. But that began to change in fall 2016.
