I actually like the hypothesis that In this first video the pilots may well have known it was a bird and where just impressed the computer could track it, with that thought in mind it completely changes how you interpret the pilots amazement...
it’s a bit conspiracy theorist, but you do wonder if either;
A. This is a bit of a troll exercise, just releasing very careful snippets to try to push the context of a ufo.
B. The more mundane that if the pilot doesn’t immediately ID the object, it gets categorised as a UFO, that does not mean to say later analysis shows it’s plausibly something fairly normal but with unless direct visual confirmation was available it stays classified as a UFO. This means it’s still a bit of a troll by the pentagon, you know, don’t want to give out any useful information, just some useless rubbish they can frame as interesting, knowing people will not do any proper analysis and jump to the wrong conclusion.
