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.
Let's sort things out.
-The tethered flag in the OP video flaps because...
...the flapping of a 'flag' is not because of the turbulence in the wind, or the presence of the flagpole," says Zhang. "It [the flapping] is intrinsically embedded in the system, as a result of the inertia dynamics of the flag interacting with the surrounding fluid flow."
The banner hanging below the balloon cluster in this video...
Note that it flaps slightly when it is moving
through the wind. For the same reason as the tethered flag. At that time, the banner is flapping
as a result of the inertia dynamics of the [banner] interacting with the surrounding fluid flow...
But when is the banner below the South Africa balloon cluster moving
through the wind? Only when the balloon cluster is ascending or descending. At that time the banner is being pulled through the air and it is
interacting with the surrounding fluid flow...
Pay attention to when the whole rig is ascending or descending, or when it is moving level with the wind. When it is moving steadily with the wind... there is no fluid flow. The banner doesn't flap.
If we assume that the UAP in the OP video is a cluster of balloons moving with the wind, not through the wind, no part of the entire structure would be in a fluid flow. There would be no rustling or trailing.
So it is incorrect to compare the physics of the flapping flag and the UAP balloon cluster.
To be honest you aren't following the physics. Just your intuition.
This is the intuitive image of a a toy balloon in the wind...
But it ain't right. This intuitive imagining comes from a common experience of what things look like when they are getting pulled through the air. An association in other words.
If you were holding a string in your hand, it would trail behind when you walk. It might also be "flapping."
A common experience.
If you were holding the same string in your hand while you were in the basket of a hot air balloon moving with the wind... it would hang limply. Even if the hot air balloon were moving across the landscape pretty quickly. Ground speed.
An uncommon experience.
That's the psychological aspect of this problem. System 1 thinking versus System 2 thinking.
https://en.wikipedia.org/wiki/Thinking,_Fast_and_Slow#:~:text=Thinking, Fast and Slow is,more deliberative, and more logical.
System 1: Fast, automatic, frequent, emotional, stereotypic, unconscious. Examples (in order of complexity) of things system 1 can do:
determine that an object is at a greater distance than another
localize the source of a specific sound
complete the phrase "war and ..."
display disgust when seeing a gruesome image
solve 2+2=?
read text on a billboard
drive a car on an empty road
think of a good chess move (if you're a chess master)
understand simple sentences
associate the description 'quiet and structured person with an eye for details' with a specific job
System 2: Slow, effortful, infrequent, logical, calculating, conscious.
Examples of things system 2 can do:
prepare yourself for the start of a sprint
direct your attention towards the clowns at the circus
direct your attention towards someone at a loud party
look for the woman with the grey hair
try to recognize a sound
sustain a faster-than-normal walking rate
determine the appropriateness of a particular behavior in a social setting
count the number of A's in a certain text
give someone your telephone number
park into a tight parking space
determine the price/quality ratio of two washing machines
determine the validity of a complex logical reasoning
solve 17 × 24
That's what I'm seeing in the comments section of MW's video. People are (unconsciously) hanging on to the System 1 model of what they intuitively picture. In other words, the stuff hanging below the balloon cluster should be trialing behind, and/or the cluster should be rustling around because of wind resistance/turbulence.
