That's certainly one interpretation.
> with the object demonstrating awareness of his presence by mirroring his maneuvers. Then he flew aggressively at it, and the object responded by rapidly flying away.
Sounds exactly like the historical reports of "foo fighters" to me.[1]
Look, I love the idea of aliens, but try to apply Occam's Razor here. What's less complicated?
a) An uncommon, but natural phenomenon in which a ball of plasma (or similar) is temporarily attracted to fast-moving, metallic aircraft.
b) An advanced, spacefaring race (or races) travel to Earth and spend over 70 years pulling pranks on military pilots.
Again, I'm no physicist, but consider something like walking through a cloud of flying dandelion seeds. The air currents created by the person walking through the cloud create little vortices that tend to pull the seeds in their "wake" toward them. That doesn't mean the dandelion seeds are "aware" of the person they're being pulled toward.
Consider also something like flux pinning, where two objects can be made to behave as if joined, even though they're separated by several centimeters or more.
"Red sprites" and similar are absolutely unreal-looking. If I saw one without knowing what it was, I'd be sure it was some kind of advanced technology too.
