The video quality is not the best, so it appears a bit shaky. However, there is clearly an object floating in the sky, and the individuals filming are attempting to zoom in on it.
Although they don’t capture the entire flight, I believe it is worth sharing with you so you can see it.
The object is seen floating towards the left, and then they try to zoom out.
I have seen this same object in other videos, which leads me to believe that it is indeed something present out there.
