It's also disingenuous to skip over more plausible explanations, including hoaxes, the memetic effect of UFO culture, classified military aircraft and disinformation campaigns, and misidentification of other mundane aerial phenomena, to assume that anything unidentified in the sky is likely an alien spacecraft.
But beyond that, I think we can agree that the conversation elsewhere in this thread demonstrates there is a whole lot of negative context which serves to drive people away from taking it seriously.
I don't, but only so long as they don't ascribe magical or supernatural qualities to physical phenomena.
It's one thing to believe alien spacecraft as an extremely unlikely possibility, and another to consider it not only likely, but indisputably so. The lack of skepticism combined with unfalsifiable claims are what disqualify him, in my view.
There does seem to be a fringe of interesting events in the field worth studying. I'm not convinced that there aren't plausible explanations for them - after all, how many "black triangle" sightings are likely to have been classified stealth aircraft? But I also think the negativity serves a valuable purpose as long as it keeps people from entertaining flights of fancy.
I'll believe the Robert Bigelows and Bob Lazars and Whitley Streibers of the world when they can back their claims up with undeniable and irrefutable evidence. Given the nature of their claims, I don't believe that's an unreasonable bar to set. Even Einstein was doubted until someone proved him right.
I'm not saying it was an alien craft, but there are a limited number of plausible explanations for an event like this and none of what you listed is a plausible explanation.
>"The disc was visible for approximately five minutes and was seen by close to a dozen United Airlines employees, ranging from pilots to supervisors, who heard chatter on the radio and raced out to view it."
It also apparently was not visible on radar or visually from the control tower. Who cares if it was 'aliens' or not, it's a damned interesting phenomena that should be studied for it's own sake.
Not taking a side, just pointing that out.
And Someone allegedly photographed it, but no one bothered to examine or release the photos?
The vast majority of people are looking at Venus or the moon or streetlights or drunken hallucinations. But we don't care about those people. We care about the 0.0003% (or whatever) of people that check all the boxes on a long list of reliability factors. And yet, that still isn't good enough for some people, because of the hugely negative pseudoscience context that this carries with it. "It's folklore!" In fact, I'll assert that a strange enough advanced aircraft could fly nuclear weapons over this country, and until our pilots shot it out of the sky and spread the wreckage across three states, it would hardly get any attention because of the context this subject carries.

Neverthless, the military does sometimes test classified aircraft in view of civilians. And they have been known to use or even encourage UFO sightings as misinformation to cover up their activity.
Fiction has to make sense, but reality doesn't always have to make sense.
And so a sensible person seeks (perhaps justifiably) prosaic explanations for everything and automatically excludes any hypothesis without a prosaic explanation (with the incredibly audacious conceit of assuming we already understand enough about the universe to make such assumptions), while the fantastical person, not as bound by the need for evidence, can wildly speculate (which would of course include nonhuman intelligences somehow visiting us over distances that are insurmountable to us currently, but might also include basically, well, anything, since without the hard-evidence requirement, you're free to get creative)
I think both of these points exist as extremes on a continuum and that they're both wrong in some capacity. I think pragmatism and reasoning and rationality are a good basis, however... just, limiting, as well.
We might advance a bit on the evidence front here if there was a scientific way to evaluate mass eyewitness testimony (individual eyewitness testimony has come under fire recently https://www.scientificamerican.com/article/do-the-eyes-have-..., but perhaps, if you multiply the number of witnesses, the errors will tend to cancel each other out and you might end up with something more like Evidence with a capital E. (This would be useful in far more areas than mere UFO observation, of course.)
What I am refusing to do is believe that hypothetical reality to be more likely than it is, based on the evidence (or lack thereof) presented and what it does or doesn't actually prove. I'm slotting it in the rank it deserves, which is slightly ahead of demons in likelihood but still less likely than everything else.
But yeah, the likelihood that it's aliens is not entirely zero.
Also, this came out moments ago. Timely? https://twitter.com/cnn/status/943105094345723904
No, because the Titanic could be proven to have existed before Robert Ballard tried to find it.
