US Military Report On UFOs: Alien Spacecraft Or Enemy Hypersonic Jets?
Neither. Visit [thunderbolts.info] and enter ufo in the search box. You’ll see a more reasonable explanation. Enter plasmoid and you can stay out of other mischief for days.
Obviously not hypersonic jets... (We don't fly without wings or exhaust).
That's human tech, we don't know what alien tech would be like.
@xenoview I might have technology that was reverse engineered from non-human technology. Obviously, I do not have alien technology. However, given my experience, I may well have suspicions over alien tech if I did see some. Are you inferring that I would not be able to recognize it? What's your point, if you have one?
