Multiple passengers on board a plane flying over Phoenix, Arizona, saw four unidentified lights outside the window. One of the passengers was able to take a photo, which his mother fortunately sent to MUFON (case 82289):
My son saw 4 purple orbs hovering over Phoenix Arizona from his airplane window on 2/22/2017. out of the airplane window. It is not a reflection on the glass because the people in the seat in front of him spotted them first and then told him to look out. He snapped a picture. He witnessed them there 30 seconds and then vanished. His picture is a really good one and quite clear.
Although the photo appears like it may show a lens reflection or anomaly, according to the witness, the UFOs were seen with the naked eye, making this case especially intriguing.
