When the US Government tells the world that North Korea has exploded a nuclear weapon than i can neither directly measure that myself nor do I have access to the data where and how the US Government knows that happens. Yet we all collectively believe that to be true.
The Nimitz incident falls under the same category. I don't know what that was but the "debunking" by Mick West simply ignores most of the little evidence we have. And so, at least 3 People (2 Pilots, 1 Radar Operator) have come forward and told a consistent story of what happened. No one has come forward and claimed they were lying (which would be the most likely explanation). The US Government is spending at least a few bucks investigating this as a result and changes their policies on reporting UFOs. During his presidency Obama himself gathered thousands of documents on Ufos[0] and told us straight up there's stuff out there we can't explain[1].
Is it possible that is all explainable? Sure, for all I know everyone is lying and North Korea doesn't have Nukes. Is it possible that we stumbled upon something extraordinary? Yes. My Argument is simply: Mick Wests "explanations" ignore a lot of the facts out there to give an answer. Any answer. And that answer will do for the people that google $topic+debunk and stop thinking there. The fact that his explanations require you to ignore evidence, believe in really, really weird coincidences and believe that all our modern sensors on f16s and radar boats fail to account for our own planes and pilots can't distinguish our own planes from flying container sized tictacs that they stare at from multiple angles for 5 minutes on a clear day.
Even if there is a very ordinary explanation for what happened, Mick West doesn't have it but his bad explanation is enough for those that don't really care and just want to reflexively debunk anything that doesn't fit their world view. If you really care, you can watch him talk with alex dietrich one of the pilots[2]. She explains to him quite well that his "explanations" for what they saw are complete nonesense. But that doesn't get you the headlines as the great debunker.
