Unexplainably loud , extremely close, hovering noise which resembles a large aircraft.This is not what I saw , but rather what myself and two dogs heard. We were approx. 1/3 of a mile west of the Fairchild airport in Lincoln Park. A wooded area that I always walk my dogs through. I grew up here in Port Angeles and have been in this park at least 100 times over the last 30 years. Also the runway at this airport is not large enough for what we heard. It was the sound of a large, (very large) aircraft. I say aircraft because it sounded as though it was right on top of us, and my two dogs stopped in their tracks and began to crawl; something I've never seen them do. I have never been behind a jet engine as it decelerated or accelerated but I thought, actually I dont know what I thought. But I do know this: I did not hear anything prior or after the initial encounter, and it sounded as if steel was being drug across the asphalt. Similar to an excavator , or a cat when their bucket is drug across the roadway when doing road repairs, Except this was a 100 times louder.
