Those are hot air balloons - the light comes from the gas flames. Ballooning is a huge thing in this part of Arizona. I’ve watched them at dusk and in the dark and this is exactly what they look like.
What’s really ridiculous is that the video is from the intersection of the Piestawa Fwy (AZ-51) and Thunderbird Rd going southbound.
That’s THE major N-S freeway in PHX-Deer Valley-Paradise Valley. Tens of thousands of people would have seen this and be able to track it.
It’s also in the PHX Class B airspace almost right on top of the 360 radial of the PHX VORTAC like 10nm from the field. That area is SATURUATED with radar and with incoming / outgoing traffic being routed over the airport and inbound for a pattern entry. The whole damn aviation world would have seen it visually and on radar.
Oh I know. It’s clever Alien Stealth Coating, but they leave the lights on the bottom to screw with the locals! Kind of a little alien humor I suppose...
Whatta buncha BS
