I live in a 14th floor apartment in downtown Milwaukee. As I was getting ready for bed this past Sat night/Sun morning, I looked out my bedroom window at the city and the moon in the SW.I saw a moving light from the west, past the Potawatomi Hotel, maybe as far as Miller Park, and thought it might be a plane coming in. Then there were more lights that came bobbing in, maybe a few hundred feet up and around ¼ mile away. At one point, there were up to 12 of them, each one of them had one light.My thought was that they were drones, but with lights? Or maybe gyrocopters. No sound. I finally thought to grab my cellphone and took a photo in which 7 lights can be seen. They seemed to gather above the 100 East Wisconsin building. Then they turned south, ascended and disappeared without a sound.((NUFORC Note: High-quality photo shows a cluster of at least seven small objects in the nighttime sky. PD))
