We took a hike around Ring Mountain. There must be some exercises going on in the area, I saw this plane circling, a Hercules and then I even saw a chopper that looked a bit like a Comanche, it was too far away. The plane looked familiar but I can’t remember what it is, ttyymmnn have an answer? It had four counter rotating turbo props and a bunch of fuel on the wings. When they flew around ahead of us and gave them a wave, then they swung back around and went right over us, no idea if they saw me but we were on the big rock on top of the hill. At a distance I thought it was another Hercules but it wasn’t. The helicopter really has me curious, not sure what it was.
