Single vehicle flying along Sandia ridgeline flying south until it turned east and left the area.I was with a group of friends out front of their house watching the sky instead of the kids in costume. I saw a bright light on approach from the north moving south towards the Airport (Sunport & Kirtland AFB). I waited for a minute to ascertain if it was a approaching VF-22, commercial airliner, or what. It stay a constant color and did not have FAA warning lights.The vehicle flew along the mountain ridge for the next couple minutes, and I pointed it out to the other witnesses, who picked up on the orangish yellow glow of the propulsion field. We watched it for the next 30 seconds until it turned towards the east abruptly (90 degree turn) and diminished in apparent magnitude and size.There was a single commercial airliner at cruising altitude at the same time heading due west.Estimate the craft to be 60-80 feet in diameter. Most likely crewed.
