Interesting video, to be sure. And I won't pretend to be able to explain it. But for this "aircraft/spacecraft" to have come from another world would mean that our "visitors" could readily annihilate us. Consider the advanced technology that would be required to reach us from who knows how far away. In such a scenario we are relative cavemen with clubs. So why such a small footprint from their visit? Seems unlikely.
If I had to bet a dollar, I'd say there's an earthly explanation for the event(s), whatever that may be. If there's more to it, then get comfortable with the idea that we're at the mercy of these aliens, and let's hope they're not some kind of Republicans from outer space.
