I don't think that's the problem, the problem is that progress in cameras is parallel to progress in drones and CGI, so we always will be able to explain away everything. If there is something to this phenomenon, no individual video is going to be enough.

For instance, if we see something like these, the explanation is going to be drones:

If we see something like these, CGI, I suppose:

This one is taken by a military grade camera at night, I suppose it could be a drone or a bird:

Because it's not reproducible it's always possible to explain away everything. It's an epistemology nightmare but I find it very interesting, specially when you have testimonies from people that you don't have a reason to doubt. I have to think if, maybe, our priors are too strong in one direction.
