Four lights in the southern sky, one stationary and the three others had a methodic illumination patternOn February 28, 2007 I was traveling from Mesa AZ to Somerton AZ (just south of Yuma AZ). I was west bound on Interstate 8. At 7:22 PM at mile marker 89.5 I saw a light appear to my left in the sky at approximately 30 degrees and what appeared to be approximately ¼ mile away. I saw this one light appear and my first thought was, "It must be a radio tower." Then a second light appeared right next to the first light. Approximately one second later a third light appeared. The lights then went off in reverse order then came back in the order in which they appeared the first time. In all there were four white lights. One was stationary and the three appeared and disappeared in a methodic manner. It was not totally black out as there was a nearly full moon. I could make out that it was a craft of some sort as it appeared to rotate slowly. It made no sound. Then, suddenly it was like someone turned off a light switch and it was gone. I got on the phone with my wife and explained to her what I had seen. While on the phone with her I was looking around the sky trying to locate the light. I looked to the North (the complete opposite direction) and way off to the north on the horizon I could see the same light pattern. In both instances the object did not appear to be traveling in a certain direction.On the way back from Somerton AZ two days later I carefully reviewed the area where I had made the sighting. There were no mountains, No towers and no homes. There was only open desert and a cow every so often.I called my dad in Indianapolis after speaking with my wife that night. I began to explain what I had just seen and in the middle of me explaining he chimed in and finished my sentence. He said he had seen the exact same thing about 30 years ago in Greenfield Indiana.Please let me know if there were any other sightings around this time period.Thank you.((NUFORC Note: We do not know what the witness observed, but the first possibility we would want to eliminate is military flares over Gila Bend Firing Range, to the southwest of Phoenix.
