Bit of a long shot but did anyone manage to get video or even just photos of this? I'm based in Cheshire so obviously nowhere near Lake Michigan but I've been following a few reports of triangular craft over the Great Lakes area for the past couple of months and this lines up really well with what others have described.
The thing I keep wondering is whether anyone noticed any sound at all. The earlier reports from around October mentioned complete silence which to me rules out most conventional explanations pretty quickly. Was it the same this time?
Also rough altitude estimate would help if anyone has one. I'm trying to work out if theres a pattern to the flightpath.
