Lights over Phoenix, again. Nothing new, it's been going on for ten years, and more. Previous to what we call "The Phoenix Lights," UFOs, strange lights, have been seen in the area for a very long time.
But with the classic UFO Phoenix Lights event of ten years ago, as we know, the official explanation -- when they finally got around to releasing one, as silly as it was -- was "flares."
And so, once again, the official explantion is: yes, flares.
