Bugs are Aliens, no really, how do they do that? Its a matter of size. I saw a demonstration of birds flying in a controlled wind tunnel experiment,
aimed at finding out how Humming birds can hover without moving directionally, and an Albatross can't flap it's wings fast. Its simply size.
The other maneuvers were not abrupt. I'm not watching ten minutes of a LunaCognita video ever again.
The last one is an air current updraft, catching who knows whatever.
At least we didn't see that one where they were distinctly two different satellites in orbit in different directions.
