Great video! Except I don't think I agree there are no turbulent forces acting on the UAP. The flag in the UAP video is moving quite a bit (We can see this extremely clearly btw, is the video focused on the ground, not the UAP?).
In your real life example it it shows that the dangling banner of you balloons that imitates streamers is moving a lot.
If we take the banner out, and just look at the weighted object that is holding the balloons in place, it creates the classic V shape of something holding balloons in place. (A)
The UAP (B) has more of a rectangle shape... certainly a strange one.
(C) is what I thought it could be made up of, maybe it's some weird makeshift surveillance drone? And like, under the ballons are cameras on a short tether, creating a taught non moving shape?
That's my best guess at what it could be, if it were balloons I don't see how it would make that shape unless it had streamers, which I think we'd see changing shape in the video.
Maybe it's a cool balloon animal, or tightly tied together balloons to create an octopus tentacle shape?
But if it was then I think physics would pull the heavier part of the balloon down, which I imagine would be the body of the balloon not the tentacles.. or at least because it had no counter weights it'd twist and turn in the air or at least be in more of a horizontal position.
Because of that I still think the things below it are not smaller balloons, and must be creating counter weight.
I think we'd see some more visible distortion in the stabilized video if they were streamers or banners.
So I think that means it must have something pulling it down that doesn't create a V shape, so that's what makes me think it's something like C
