Are you referring to the documented cases of UFO sightings by the US navy?
AFAIK there were also numerous pilot testimonies and radar logs to prove what was happening.
Or is it a different case?

Here he goes through why the glare rotates while the horizon does not (and recreates the phenomenon): https://www.youtube.com/watch?v=ka_bX9Hx1H0
Here he highlights the relevant gimbal information on the Navy display that explains the "sudden" movements of the UFO: https://www.youtube.com/watch?v=U1di0XIa9RQ&t=251s
He's a retired developer who is now a science writer and skeptical investigator (just to give you an idea of where his expertise/bias may lie)
Unless there's some unmentioned specific expertise, that's not a very high bar, relative to what he's trying to discuss.
His videos do a decent job of replicating the behavior seen in the UFO videos in a simple way and will give experts in the area a starting point to agree/disagree with his conclusions. Especially with the simple descriptions of the gimbal behavior/limitations in range of motion paired with the data given in the view of the video.
