Didn't see it myself, I'm based in Glastonbury so a bit far from Phoenix! But I'm curious - did you manage to get any photos or footage? I've been trying to improve my night photography for exactly this kind of thing and I always wonder what settings people are using when they catch something.
Also was it completely silent or did it make any sound? That seems to be the thing that separates the genuinely odd sightings from military craft in my experience, though I'll admit I'm still fairly new to all this. The triangular shape keeps coming up in reports and I cant work out if thats one type of craft or several different ones that just look similar.
