The Air Force tracks everything in the continental airspace that rises into the air. They know exactly what these things are, and where they come from. The drones make noises like “lawnmowers.” That means they have internal combustion engines.
So:
-They are terrestrial.
- We know where they come from and where they go.
If those things are true (and I believe they are), then they are our drones and we are testing them against our own bases and staff.
This reporting is specifically used to garner an emotional response. It’s silly.
That would be my guess also, they are ours and it was and is an exercise. During the Predator Drone testing years ago I was flying to AZ in my 172 and a Predator with a 182 chase plane pulled along side me for about 30 miles across the desert, real cute drone.
