There may be more to this than meets the eye. Reports of multiple sightings of multiple drones, from ~9pm through to at least ~3am.
That's probably not some kid being stupid, or a prank. That's starting to look like we need to at least consider the possibility of a planned attack on infrastructure; a takedown of the airport. Maybe even a rehearsal; now imagine the same thing happening at several airports across the southeast; chaos cubed.
