I've seen the powerline choppers. There's a stretch just a bit north of me. These guys didn't look like the ones I see on the powerlines. Two of them flying not along the lines? I couldn't get to a camera in time and they were too low anyway the trees to my north blocked them. I'll have to check the PD.
Got an email the other day stating that First Energy would be out performing inspections and repairs of their wires with helicopters for about a week in the Streetsboro-Twinsburg area. A small portion of those wires go through the southern part of Aurora, so that's why I was copied. -in case the locals get nervous that aliens are attacking, I guess.
I saw that one along the powerline that crosses Richmond and Broadway. These were not like that one. I have a blurry picture of the powerline one.
The ones I saw going right over my home had refueling probes on the right side of the nose, so they were definitively military. I looked thru pictures on the web but the closest thing I could find was a CH-53. Maybe, maybe not.
I just head a Sikorsky flight testing on 123.025 and with approach on 125.350.
