I can't see your original comment because it's flagged, but I'll assume it's some sort of anti-vax flag hanging from a Southwest plane.

So... so what? The explanation from Southwest's CEO makes sense and matches up against a ton of publicly available data.

On the other hand there's evidence of at least one pissed off pilot (who, none-the-less, showed up to work?)

But, again, all that other data still exists.

So. Either there's a vast conspiracy that involves NOAA, the FAA, airport admin, air traffic controllers, Southwest, the pilot's union, etc. Or else one dude flew a flag and also there was a massive scheduling failure and the two are unrelated.

I genuinely couldn't have asked for a better exemplar of my original post: seeing a ton of verifiable data vs. a single anecdote and choosing to implicitly believe in a vast conspiracy because the anecdote touches one's feels the right way.
