My daughter woke me up around 3:00 am and said she was scared to death. She said it sounded like the air conditioner unit but then it started pulsating. She had looked out her window and saw an unknown craft. We returned to her room and I immediately saw lights in the sky. It was hovering above the Missouri River, about 2 miles away. She said it was much closer when it woke her. I thought it was a helicopter at first but the lights were odd. I think there were 3 lights but the movement was unnatural and hard to count. It appeared to be boomerang shaped with lights on wing tips and front and it was panning back & forth. That was the only way to the lights changing from 3 to 2 then 3 and so on. I tried to figure a flight path when it just vanished. It was also very unnerving since we live around 10 miles from the Callaway Nuclear Plant. I had forgotten about it until I saw the episode of Hangar One covering Missouri hot spots.
