> Frankly, a much less reaching theory at this point is that we simply don't know what these things are, have completely failed to determine it, and can't safely conjecture anymore they are human created or purely natural phenomena. This is a perfectly suitable place to be given our place in the universe and our current level of understanding, and doesn't require any further leaps to explaining their origin beyond "we just don't know." In terms of action, it does mean we should try to find out more if we haven't yet fully exhausted our ability to do so. Hard to say, given the evidence, if our government has done so, but civilian industry certainly hasn't.
This is compatible with dvh's theory AIUI, which is not about explaining this particular case but about explaining why we're hearing about this stuff. If the government wants people to report UFO sightings, and they're encouraging it by amplifying instead of suppressing certain UFO reports, why would they shine the spotlight on the reports that are actually their top-secret drones? They'd pick something like this, where no one actually knows wtf it is. They don't have to fake the incident, they just pick something weird that happened and say "hey media, check this out".
