The paper is by three Ukranian astro photogrammetrypeople .. I was going to comment on "ships" for the bias but figured I can mark that down to non native English speakers and some translation issue.

Nothing in the eight pages screams "we believe in aliens", it's essentially about not yet catogorised observed phenomona high up in the troposphere.

With limited data on fast objects that appear in only a few frames they write about two classes of "things".

The earth, of course, sees an infall of roughly 48.5 tons of material per day of various sizes and composition, much of which never reaches the surface directly, instead breaking up and falling as dust.

The phrase “squadron of ships” seems like deliberate word choice. And to me, “squadron” is a more alarming word than “ships,” because it implies cooperation between multiple intelligent entities. But the paper does not describe much compelling evidence for any intelligent “swarming” behavior, so I interpreted the word choice as bias.

The crescent shape looks like it could be side view of the ionized part of a shock wave (maybe there’s a better word for it).

The paper isn’t clear about this, but the crescent in that image is the moon, AFAIU. They’re using it as a baseline for luminosity of the UAPs, which are the multiple (less bright) white speckles in the image.
