Bit of an odd one to ask but - was anyone recording that night? I'm based in the UK so obviously I wasn't there, but I've been trying to piece together a timeline of triangular craft sightings across the US over the past few months and this one's come up in two separate groups I'm in.
The reason I'm asking specifically about footage is that the Phoenix lights incident back in 97 had so many witnesses but the video quality made analysis really difficult. If someone got decent footage this time even on a mobile it could be worth running through some photo analysis tools to check for things like rotation, light spacing, altitude estimation.
I do paranormal photography myself so I know how much detail you can pull out of even fairly poor quality images if you know what youre doing. Happy to take a look at anything if people want a second opinion on what they captured.
