So will speaking specifically to the white orbs being seen any guess as to what they are.
It’s a known fact we have stealth technology. We have hovercrafts. As far as I know hovercraft don’t travel at commercial airspace heights. They are a few feet from the ground. As far as I know our stealth aircraft don’t “hover” like Harriers. Im definitely sure that neither of them are completely silent.
In fact silent aircrafts are still on the design table

And it doesn’t appear they are going to be silent, but rather would be "imperceptible" beyond the boundaries of an airport.
I live in Phoenix and I’ve seen the “lights” twice now. The first time I thought it was just a large version of the stealth bomber like ½ mile or larger. My mind wasn’t registering that it was of ET origin.
The second, years later it once again appeared and flew over my neighborhood. The thing looked like it was a full mile wide. It blackend the sky for a moment it was so large. It was completely silent- completely silent. I would say it flew over my neighborhood, but it resembled floating. Luke AFB’s official story was that it was flares- that is absolute bullshit.
Could it have been the hugest hot air balloon in history that was in a triangular shape with lights on it, yes. I would believe that over it was a secret military craft that the government was worried about keeping secret. Everyone that was home on my block saw it at the same time.
