So they have caught something(s) on infrared/FLIR, which is passive reception, the same for visual/optical, yes?

But no active reflections from some radar somewhere?

I think this is just a massive PsyOp, consisting of at least two invisible BEAMS of whatever, sweeping the skies like searchlights tightly synchronized, making the air glow where they meet.

And gazillions of newsbots chasing the next headline, like cats hunting the dot of a laserpointer...
