I'm skeptical of the part where it went to the CAP point. First, it was apparently only detected at the CAP point by the USS Princeton, it was gone by the time the jets arrived so we don't have multiple confirmation. But more importantly, how did the craft know to go to the CAP point? Even if the jets were bearing in that direction at the time (and I don't think they were) how would it know the distance to travel? Was it listening in on radio chatter, meaning they have reverse engineered our communications protocols, broken our encryption, and understand enough of our language and technical jargon to determine where to go? Were the exact coordinates of the CAP point even discussed over the radio while in the presence of the craft? And the whole thing just seems weird to me. If you're an alien vessel visiting our planet, it seems like you're either going to try to make contact, or ignore people and just gather samples. But this? Just sort of bothering the US Navy? You could argue it was gathering samples of ocean water or something. But then why go to the CAP point? That can't be to collect scientific data. And that doesn't make sense as their attempt to contact us. As I mentioned above, they'd have to have a lot of knowledge of our language and communication to know where that point is, which means they know enough to simply make radio contact.
