Well almost is doing a lot of heavy lifting, the case is all circumstantial. But I say that both because of a Reddit post that makes a strong case that at least some portion of sightings are a specific model of navy drone, and more so because their being military is the only situation where the government response makes sense to me.

If they were an enemy’s, one would expect them to be shot down. If they were an ally’s, they would need a damn good reason to be here and an even better reason why people can’t know. Maybe they’re a private citizen’s, but I struggle to imagine why a private entity would have a fleet of large drones that they covertly deploy along the coasts, and why our government would abide that. So as I see it, the two options that make sense are that they’re an enemy’s that we can’t shoot down for some terrifying reason, or they’re ours.
