2000-11-28 - Phoenix, AZ - Triangle

I was in my back yard petting the dogs when i heard a loud,low rumble of a passing jet plane.When i looked up i saw a huge triangle craft with red lights on each point.I watched the object move to the NE for about ten seconds when it began to spin in a clockwise motion.The object dissappeared behind some trees after about 30-40 seconds.The amazing thing is that the air was full of air traffic at the time.I live close to Deer Valley airport and see many planes every night, along with big planes heading or leaving from Sky Harbor airport.Many of these planes had to see this object as it flew among them.There were no green running lights and no white tail light to be seen.If it was the military they were flying with illegal lights and over a a metropolitan area.
