Didn't see this myself obviously (Norway here) but my mate in Scottsdale sent me a video that same night, around 22:15 his time. Three white lights in a loose triangle formation, completely silent, moving way too slow for a conventional aircraft then just stopping dead. No blinking nav lights either which is the thing that gets me.
Has anyone actually managed to correlate this with flight radar data for that window? I keep seeing these triangle reports and the "military drone formation" explanation gets thrown around constantly but nobody ever actually links it to confirmed operations in the area.
Also wondering - was there any colour shift or were they solid white the whole time? The video my mate sent was pretty grainy so hard to tell. These details matter and people always forget to mention them.
