I think mariners tend to be more skeptical about UFO/UAP sightings than non-mariners as we see a lot of weird stuff that’s sometimes difficult to understand. Be the same for pilots I’d assume.
But even if 99.99 % of sighting can be explained or dismissed that still leaves 0.01% that could be more difficult to understand.
I’ve never paid them much mind till now, but after reading the Wolfram article in the OP I’m not so sure.
Perhaps what is being seen (you saw it here first) is not the craft itself but the effect of the craft. Like seeing the wake of a boat passing but no boat in sight.
That why the aliens sometimes are not concerned if it’s seen. Like the boater speeding in the “no wake zone”, they just don’t care.
