Mystery UFO sighting that baffled police captured on camera in Pennsylvania

There is no question in Stephanie Wilkerson's mind about what she saw in the night sky this week. When a giant circle of flashing lights appeared over her Pennsylvania home, she ran to grab her neighbour who brought his binoculars to take a closer look. After the lights started to change colour, the pair called 911 and began filming the strange sight on a mobile phone. In an interview with ABC New, Stephanie said: "I thought it was a plane until I realised it wasn't moving. I watched it for about 20 minutes and I started noticing it changing colours," (S.O.T.T)
