Small silent red dot doing maneuvers over Amish farm

I'm visiting my parents in their 55 and up community from NH. I was walking around the paved path that marks the perimeter and when I was on the far side from my parents, the west side, I saw a red dot moving silently north. I look away for a second and it was gone. As I continued I got closer to my parents place and up in the sky over the farm I see the light again, this time moving east to south. As it did it made a harder bank and came back at me, then almost immediately banked back around on its original heading. I looked down for 1 second and it was gone again. I could see and hear other aircraft in the area and I've worked on a flightline in the Air Force, I've never seen anything make that kind of maneuver that tight and not have strobes on it or make a sound and just be a small silent red dot in the sky over an Amish farm.
