A helicopter flew over my house about two weeks ago. I did not see it, but it was about 100’ high and did a circle around a friend’s house. As it flew over, my wifi cut out, probably due to electrical interference.
I did not see the flight but my friends did and they thought they saw USG (USGS??)
It took me some time and then I found this site. I don’t want to give away personal information, but would like to ID the Helicopter that flew over my house with doors open. The helicopter was white with red at the bottom, similar to some Bell 412’s I was able to find but I don’t know much about aviation
This is the 2nd time this has happened though.
The last date was  5/25/21 at 9:30 - about 20-30 miles north of milwaukee.
