Tyler Rogoway at the The Drive dot com WarZone posted a remarkable article yesterday about this.It includes several important videos and links.
Here's the money shot:
...When it comes to the so-called "Tic Tac" incident that involved the Nimitz Carrier Strike Group off the Baja Peninsula in 2004, conclusions that are nearly impossible not to draw from it are so reality warping that even the forward-thinking aerospace community doesn't seem to have even begun coming to terms with them. The main revelation is that technology exists that is capable of performing flying maneuvers that shatter our perceptions of propulsion, flight controls, material science, and even physics. Let me underline this again for you, the Nimitz encounter with the Tic Tac proved that exotic technology that is widely thought of as the domain of science fiction actually exists. It is real. It isn't the result of altered perception, someone's lucid dream, a stray weather balloon, or swamp gas. Someone or something has crossed the technological Rubicon and has obtained what some would call the Holy Grail of aerospace engineering. This reality is very hard to process for many. There is always an out for some in the form of claiming an odd impromptu conspiracy or some hollow explanation that doesn't pass muster beyond the first paragraph, but in the end, it happened. As uncomfortable as that fact is, it's reality. So, we need to use this event as a lodestar going forward when it comes to evaluating and contemplating what is possible and where truth actually lies.
