Four unknown bright lights flying in a square formation towards Yuma, Arizona were seen by numerous people a few days ago. Witness: Yuma Proving Grounds does military testing but I've has never seen like this in all 23 years of living here, I wish I could've recorded the 4 flying in a square formation but I couldn't pull my phone out fast enough after I was done being in awe. So the question is what are/were they... aliens or maybe military test? IF YOU ENJOY THIS SITE PLEASE TELL OTHERS ABOUT US...SHARING IS CARING Start the discussion, leave a comment below
