Interesting video, but I'm not convinced.
Firstly, at the end - when the object shoots off the screen of the targeting pod, it looks more like the pod is at it's gimble limit, and because the plane is banking it exceeds the tracking limit, giving the appearance of it flying away, when it's just the TGP that's lost it's track.
Regarding the churn on the water, followed by the tic-tac shaped thing. I think a more reasonable explanation is a submarine performing missile drills and firing some sort of test missile. Combine that with a lack of communication, throw into that a bit of confusion, multiple people, multiple reports - and it seems more likely this was far closer to home, than some ultra-advanced and secretive thing, or even extra-terrestrial.
Of course I can't prove any of this, I just think it's far more likely.
