"The Four Viable Explanations for UAP" & couple extra I added

I would have said "a combination of A and B" if that were available. It's well documented that some amount of systemic deception has occurred, but I doubt it accounts for the majority of this phenomenon.

I think the bulk of instances are most likely to be observational errors of various sorts.

Look forward to the follow up post.
