The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
I was watching fireworks out my window. i live under a path that many airplanes take to get to oâ€™hare. for reference i was facing out toward the lake with oâ€™hare behind me. many planes flew by that night, as well, but these lights appeared to hover in the distance. sometimes i saw one or two and i wasnâ€™t sure if i was seeing someoneâ€™s drone, but at one point the lights seemed to be in formation. the lights would go away when people stopped shooting off fireworks for a few minutes, and then often seemed to reappear once people resumed the fireworks. sometimes i saw the lights and the planes at the same time.
