Interesting, I occasionally hear a similar sound here in Portland Oregon. When I hear it I always initially think it is a jet aircraft, but then I will notice the rhythmic pattern. Is it possible for jet aircraft to produce I kind of wavering sound? The pattern is usually stable and fades in and out.
Anyways, thanks for bringing this to our attention OP. Seems like I hear something about these sounds every once in a while then people quickly forget. I reckon it is due to all the hoaxed videos on Youtube. No to say all of them are hoaxed since they occasionally appear on the news, but a good majority are. Really sucks too because all the hoaxes seem to discredit the authentic ones. Hmmmmm...... Disinformation perhaps?
