I was just getting off of the night shift on New Years night when I saw in the distances as though this large plane coming into the city. I stopped along the road because I wanted to get a better look at this gigantic large but it took only a second to realize it wasn't a large plane. It was enormous disk shaped flying object with three levels of lights around the center that changed color every few seconds from yellow than to green,than to purple,than red. It could travel within seconds multi directions. It made a soft humming sound as it came over the city of Mcallen. I looked around to see if any other cars were out so they could also be witnesses but since it was a nite of party there wasn't another person in sight. It hovered over a tall building downtown called the towel for a minute or so than disappeared. I went as fast as I could home and told my husband.
