Bit late to this thread but genuinely curious - did anyone record it? I'm over in Suffolk so obviously wasn't there but I've been tracking triangular UAP sightings for a few years now and Phoenix keeps coming up as a hotspot.
The reason I'm asking is I've got a mate in Arizona who messaged me Wednesday morning saying he saw something weird the night before but didn't know what time exactly. Didn't get a good look at it though, just said it was silent and moving way too slow for a conventional aircraft.
What I want to know is whether the lights were at each corner of the triangle or more clustered towards the rear? That detail seems to matter when you're trying to work out if these are the same craft type being reported elsewhere. There's a pattern across multiple sightings and the light configuration keeps coming up as a distinguishing factor.
