When it (the situation) closes down an Air Force base airport, and they don't handle it as a direct threat and wipe them from the sky, there is definitely more to the story.
If they are military or government "testing", why TF are they doing it over populated areas instead of the thousands of miles of desert available?
What benefit of testing over people, unless there is a specific tech that HAS to be tested over a population?
Tested at NIGHT.
Or, are they using them to actively search for something?
My questions sound like a search for a conspiracy theory, but they are more about drilling through the logical possibilities to figure out what is really going on.
There are only so many reasons a "swarm" of very large drones would be up like that, and only at night.
