Wasn't there myself (I'm up in Inverness, Scotland so a bit far from Arizona lol) but I've been following the Phoenix area sightings quite closely lately and this matches several reports I've got bookmarked from the last 18 months.
Quick question for those who saw it - was the craft completely silent or was there any low frequency hum? The reason I ask is that the triangular UAPs reported over the UK tend to split into two categories, the totally silent ones and the ones with that subsonic rumble people feel more than hear. I've spoken to a few witnesses up here who described it almost like a pressure in the chest.
Also, was the underside uniformly dark or did it have any kind of surface texture visible? Even at night with enough ambient light sometimes people catch detail.
Genuinely trying to build up a comparison database between European and North American triangular sightings because I think the behavioural patterns tell us more than the shape alone.
