At a restricted airfield at a quiet National Guard base in central California, researchers from the Naval Postgraduate School have loaded a drone they call a flying wing onto what looks like a giant sling shot.
The drone soars up into the air and settles into a racetrack pattern. It's up so high it's hard to see, but the sound is inescapable — like a buzzing bee. With the launch of several more, the buzz grows louder as they all settle into that racetrack pattern.
The aim is to get 24 drones into a swarm and have it behave like one.
