Grey, triangular object with no lights moving across the sky.My daughter and I were looking at the sky tonight when we saw something moving across the sky. I only noticed it because it blocked out the stars. I looked at it through binoculars and saw that it was triangular in shape, no lights, was grey and very smooth, and made no noise whatsoever. It was bigger than a commercial airplane, but I could not tell exactly how big. It was moving very fast, and the movement was in a single direction and very smooth. It was moving from Fairbanks area, over Ft. Wainwright going towards North Pole.
