Anyone else notice the weird triangular lights over Phoenix last Thursday night?

Didn't catch this myself but a mate in Sheffield messaged me about something similar on Friday morning, said he'd seen three points of light holding a perfect triangle formation for about 4 minutes before they just went dark simultaneously. No drift, no sound according to him.

My question is - does anyone know if there was any scheduled military activity over Arizona that night? I always try to rule that out first before getting too deep into the weeds. USAF does a lot of testing in that region and some of the newer drone swarm tech can genuinely mimic this kind of pattern.

That said the simultaneous disappearance is the bit that gets me. Flares drift and fade at different rates, thats just physics. Perfectly synced cutoff is harder to explain away. Anyone actually on the ground in Phoenix with video?

@ActualApparition the 4 minute sustained formation is the key detail here. Random drones or flares don't hold a perfect equilateral triangle for that duration, they drift. What's your mate's rough lat/long for Sheffield? Because triangular UAP reports have been clustering in a surprisingly consistent band across northern England and the midwest US over the past 18 months and if this lines up geographically it adds to a pattern I've been tracking.

The Phoenix lights comparison is obvious but worth noting the original 97 event also had witnesses reporting a rigid formation that moved as a single unit rather than three separate craft maintaining proximity. That distinction matters a lot when you're trying to rule out conventional explanations.

Did he notice any sound? That's always my first question.

@TheAENurse yeah the duration is what gets me too. Four minutes is a long time to hold any kind of formation, drone swarm or otherwise, especially if theres wind at altitude.

The Phoenix thing keeps coming up though doesn't it. Goes all the way back to '97 obviously but theres been a steady trickle of triangle reports from that area ever since. My gut says its worth cross-referencing with FlightAware for that night, rule out the boring stuff first, then see whats left.

@ActualApparition - did your mate in Sheffield get any footage or was it just visual? The Sheffield sighting is interesting to me because triangle formations over the UK tend to cluster around certain corridors and I'd want to know the rough direction it was travelling.
