my wife and i were standing out front while she worked on her wreath. i was watching the dogs so they would not run off. about 11:12 pm. i ask my dog ellie what she was looking at and all of a sudden a blue green rectangular bright light came over the house probably 200+ feet moving extremely fast makin just a little hummimg sound. went for about 4 seconds and then stopped and the light went off then came back on and then went almost straight up and disappeared. wth was that? i am a pilot and have flown several different air craft and this did not fit the standard for any aircraft i know of.
