Glowing UFOs over Vestavia, Alabama

On April 5, 2014, in Vestavia (Alabama), a brother and his sister have seen multiple unidentified flying and luminous objects that moved rapidly in the night sky.

Eyewitness states:

My sister called me and told me to hurry outside and see the dozens of lights in the sky. She joked that we were being invaded.  I went outside my house and couldn't see anything. I live on top a mountain and it was cloudy/foggy. She was at my mother's house about 8-10 miles away. She pulled in driveway, got out of her car and noticed the lights immediately. Said they were moving fast and there were dozens at first. She sent me a pic to see if I could tell what they were. I have no clue.
