Was letting the dogs out when I noticed a light moving from my North to my West. When I looked up a few minutes later, it had turned Southeast toward me. I checked Plane Finder and saw nothing in that direction so I zoomed in and started recording. As it went within a couple of miles of me, I heard almost nothing. You can hear the light buzzing in the video - almost like a prop RC plane but much lower frequency. Very strange. Don't have an obvious explanation.
