Didn't see it myself but I'm only about 3 hours out in Roswell so obviously not the right location, but I'm curious - did it make any sound at all? That's usually the first thing I ask when people report the triangular ones because the silent ones behave completely differently to anything I'd class as conventional military.
Also what was the altitude like, rough estimate? Because we've had a few reports come through here lately of low-altitude triangles and the consistency in witness descriptions is starting to get hard to ignore. Like were the lights at each corner pulsing or static? Thats the detail that keeps coming up in the Phoenix area accounts I've been collecting.
