Possibly, although I don't get the rational of flying clandestine warplane in the commercial alley. But who knows , maybe they are testing the F-U series.
And I don't get the media attitude about covering this. Even if you strongly believe its not an alien craft, isn't there a huge story about security gap or pilot insanity?
I do admit that I'm a UFO junkie. We barely understand the universe, our place in it, life's origin to conclusively state that we are alone. Maybe Musk is right that the odds of this world being a simulation are higher than this being a base reality.
