That's what AARO would call "a balloon-like entity". It looks like a balloon and moves like a balloon, but as it's in the LIZ, you can't prove it's a balloon.
Note the direction of motion in all three cases.
Exactly in the opposite direction to the plane. This is a common illusion in UAP videos where there's a large magnification, and you are tracking an object. A balloon that is
not moving at all, that's much closer to the camera than the plane, will appear to move in the opposite direction to the tracked object. Maybe it's coincidentally moving exactly opposite, but more likely it's not moving, and the camera motion gives the illusion of motion.
You see this when the clip is stabilized on the plane
and then even more so with an echo
So it appears to be a white object, not moving in the air (just moving with the wind, so zero airspeed). Basically, there's nothing to suggest it's not a balloon - you just can't prove it.
