Are the airplanes getting louder and lower?
No. And maybe. Objectively speaking, individual aircraft flyovers near Sea-Tac Airport are not getting lower or louder. (Before you click away in disgust, note that some of our members live as low as ‘760’, ie. when correcting for sea level less than 400 feet directly under the belly of an aircraft. No one is more -
