Didn't see this myself (Dundee's a fair distance from Arizona lol) but genuinely curious about a few things if anyone caught it on camera:
What was the spacing like between the lights? Fixed triangle formation or were they shifting position relative to each other? That's usually the first thing I try to establish - rigid formation suggests one craft, variable spacing suggests multiple objects or drones.
Any sound reported? A lot of the Phoenix sightings historically have been silent which rules out most conventional explanations pretty quickly.
Also wondering - did anyone manage to capture it on anything decent? Phone footage is usually pretty useless for this stuff but if someone had a dashcam running or even a basic DSLR on a tripod that would be worth looking at properly. I run a Hikvision camera setup at home pointed at the sky most nights and the difference between that and phone footage is night and day.
The reason I'm asking is I've been cross-referencing a load of triangular UAP reports from the last 18 months and there seems to be a loose cluster of similar descriptions - slow moving, silent, low altitude - across the southwest US. Trying to work out if last Thursday fits that pattern or if it's something more mundane.
Anyone who was actually there, what was your gut feeling in the moment? Sometimes that's worth noting even if it sounds daft.
