I was getting into my car. I heard a low loud hum. I looked up in the direction I heard the noise. Above the power lines I saw a huge dull gun metal grey triangular boomerang shaped flying object. Each wing had a light of amber like red. It hovered momentarily, cloaked…meaning all I could see were the lights and a shape that blocked the stars as it sped off at a high rate of speed. This all happened in about a minute. It was not a plane. It was 3x the size of a low flying plane. Before I got into my car I noticed about 4 helicopters circling in the area, which is not an abnormal event around here.
