Okay, maybe they are actually looking for or at something when they are hovering over my area at a low altitude. But dang it they are loud, and sometimes at different hours annoying.
The day after one of them whirlybirds has been flying overhead I check Airscene.com, hit ‘flight tracking’ then flights to try to find the annoying thing and see how low it was flying. Typically the police copters are UNK, but I know what they are and when they where here, I just can’t gauge how low they were flying. Wednesday, around 4pm, the skies were busy and UNKs flying below 1000 feet.
