UFO Sighted On 4th July Over Renton, Washington

My daughter and I were out watching 4th of July, 2012 fireworks in the neighborhood when we saw an orange and red glowing orb in the sky. At first we thought it was a plane or a helicopter as we are close to SeaTac but quickly realized that was not the case as we saw air crafts in the area. We zoomed in with the binoculars we had brought with us also we live in Renton, WA. Some people standing
