On May 8 2015,walking my dog north of my home in Sunshine Valley NMI saw a large flying object silver and cooper in color,and made up of two triangles shapes.The silver part making up 2/3 of the overall length.The silver part was very bright and shinny,and I could not see any details to surface of the object.The object was coming out of the west over the Rio Grande gorge headed east approaching Ute Mountain.As it got closer to the mountain I noticed it made no sound,and it seemed to be moving to slow for something that size,more than a hundred feet. And at that point I could tell it did not have wings.I was in Air Force and my father was a pilot,so I feel I know a little about aircraft,and this was something I had never seen before.when this object got directly over the top of Ute Mountain,it disappeared in less an a second.It did not fly behind the mountain or fly out of sight,it disappeared.I don't have pictures or a video for you I wish I did.I am not real sure how I feel about seeing it.I hope in my live time we have the answers.
