In the footage it is very clear that UFO that appears passing over the Plane when it approaches to land, a really FANTASTIC video, you can see in the Video below the UFO at 17:00, you can also observe several birds in the place.
We analyzed the video several times and we can see that it is not a balloon or a drone, a “100% authentic” video without any pixel changes.
Note: If it were a balloon only when approaching a plane of that size, there would be a huge air displacement, so the balloon would tend to rise immediately, which did not happen when it passed over the plane. So the possibility of being a BALLOON is DISCARDED.
It looks like they really want to show off, saying:
“Look, we are here in broad daylight”
