I was in the backyard of my house facing south, when a shiny donut shaped object appeared from the treeline. i have never seen anything like it before. i was a little scared at first. it seemed to flip and spin at random. gained altitude, then passed almost overhead. its motions smoothed out as it headed north. sometimes it appeared shiny, and reflected the sunlight, other times it was appeared black or dark. it moved north from south of my house until it dissapeared into clouds north over albuquerque. i wold guess it covered about 20 miles in two minutes, untill we lost sight. my 10 year old daughter also witnessed the object.
