I was working outside and around 11am on 9-23-2020 we heard a very loud jet engine come from the south to north with no object ever spotted. it was a cloudless sky and i looked to the north to look ahead of the noise and saw nothing. the person i was with saw nothing either. after talking to several guys i was working with, none of them saw anything. i spoke to my wife who was out at the time, heard and saw nothing either. it sounded like a jet that was flying very low and the oddest thing was that about the time the sound got to overhead or a little past, the sound went silent for 3 seconds then came back like it was paused.
