Bit of a long shot but does anyone have footage from that night? I'm based in Birmingham so obviously wasn't there myself, but I've been cross-referencing a few sighting reports from that area and Tuesday keeps coming up specifically. Trying to work out if theres a pattern around that lake or if its just coincidence that multiple reports cluster around the same dates.
What direction were the lights moving, if at all? That detail tends to get left out of these reports and its actually one of the more useful bits for ruling things in or out. Stationary vs drifting vs erratic movement tells you a lot.
