This video of a triangle shaped ufo was filmed over Glendale, Arizona in November 2012
Witness report: I was going over some of my photos from an event called Glendale Glitters in Arizona and I noticed something really strange. What appears to be three orbs out in the middle of the sky. The second photo shows them from a different angle. Flying orbs have been seen in Arizona lots of times and one good example is the Phoenix lights.
