No, we're talking about unidentified thing. Some of which have accounts that seem extraordinary, but may not be. I don't know about the French one, but the Nimitz one the accounts don't really make sense. Also, the radar detected something but it doesn't provide any evidence for something extraordinary. The video does not. It shows something explainable by mundane possibilities. The only thing that does really is the first hand account.

Now, you may say Fravor is an expert so he can't be mistaken. I'll agree he's an expert, but so are doctors. Have you ever heard of a doctor misidentifying a desease or anything? They're just dealing with mostly static things in the decently well understood and observed human body. They aren't flying at high speed circling around an object while descending towards it while keeping track of everything else around and also dealing with everything in the environment with basically no depth perception because it's too far away and has no object of known size nearby to use as reference. Its easily possible he could be mistaken with what he saw that day, and especially considering he only recounted it, what was it, 20 years later.

No one can prove it is mundane, but equally there's really no proof it's extraordinary. There's some evidence that's mostly based on recall from an old event which seems to have some issue with what other people recall happening.

Regardless, it's a potential hazard to pilots that needs to be reported and taken seriously to ensure pilot safety. It's almost certainly not something directly dangerous though, or anything particularly special, but we'll never know.
