The skies over the United States were a little more crowded than usual following a test by the Department of Defense that sent more than 100 drones scattering across the sky, according to a report from the BBC. A total of 103 of the miniature, unmanned flying vehicles were released from a trio of Three F/A-18 Super Hornets, a popular Navy fighter aircraft. Called Perdix drones, the flyers have a wingspan of just 12 inches and move entirely autonomously--no human control required. Footage of the devices in action from October 2016, taken from Naval Air Weapons Station China Lake, was recently released by the Department of Defense. In it, the drones can be seen being released into the sky and swarming together, making use of the collective brain that controls them.
