Arlington Police Chief Will Johnson announced Thursday that the Federal Aviation Administration has given the city permission to get the wheels moving on this project in late February. Police are quick to emphasize that these 4- to 5-foot-long aircraft aren’t the same as military drones: “They’re unmanned aircraft,” Arlington police spokeswoman Tiara Richard said. The unmanned craft, which can fly at speeds up to 40 mph, are intended as a more affordable alternative to traditional police helicopters usually employed in search missions.
