My husband and I were driving north on Estrella Pkwy. As we drove over the mountain towards MC 85 we saw 5 very bright lights in a row. We both stated they looked like planes lined up to land in formation, but as we drove more north we saw the lights were hovering and not anywhere near an airport. I told my husband to turn right (east) on Van Buren. As we headed toward the lights they started to disappear. We noticed at least 2 helicopters circling around the lights. One by one they seemed to vanish. My husband and I were very bewildered.
