Dark grey, nodular, triangular craft passed overhead above tree line and made absolutely no noise.I just discovered your site for reporting UFO sightings. I don’t know the exact date now, it was a couple of weeks ago, the end of August 2016. I was in my backyard in Albuquerque, NM at approximately 10:30am when I noticed a large shadow overhead. I looked up and a craft about the same size as my house was passing overhead just above the tree line, west to east, and passed by in about 5 to 7 seconds before I couldn’t see it any longer because of my neighbor’s house and trees obstructing the view. The craft was dark grey, triangle shape with no visible lights, markings of any kind, or landing gear, and made absolutely no noise as it passed over.I live in a glide path for commercial airlines, south to north, and see planes every day. They make noise. They have smooth body fuselage and wings. This craft was not a plane. It was more triangular in shape, and it was not smooth underneath like planes are. It was very nodular. I’ve been looking at photos online to see if there is anything like what I saw posted, but can’t find anything in real life. Closest thing was the Millennium Falcon from Starwars.I am retired, 67 year old male, with good vision and sound mind.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
