Didn't see it myself as I'm over in Cheshire, but my cousin lives in Milwaukee and she messaged me Thursday night saying she'd seen something unusual over the water. She described it as a cluster of orange-ish lights that sort of hovered and then split apart, which honestly sounds a lot like what a few people are describing in this thread.
What's the rough time you all saw it? She said around 10:40pm but she wasn't paying close attention. Also wondering if anyone had a camera or dash cam running, because eyewitness accounts are great but footage would really help nail down whether this was one object or multiple.
Has anyone cross-referenced flight radar for that time window? Thats usually my first step before jumping to conclusions, rule out the mundane stuff first.
