Last August, U.S. Navy operators on the ground lost all contact with a Fire Scout helicopter flying over Maryland. They had programmed the unmanned aerial vehicle to return to its launch point if ground communications failed, but instead the machine took off on a north-by-northwest route toward the nation’s capital. Over the next 30 minutes, military officials alerted the Federal Aviation Administration and North American Aerospace Defense Command and readied F-16 fighters to intercept the pilotless craft. Finally, with the Fire Scout just miles shy of the White House, the Navy regained control and commanded it to come home. “Renegade Unmanned Drone Wandered Skies Near Nation’s Capital,” warned one news headline in the following days. “UAV Resists Its Human Oppressors, Joyrides over Washington, D.C.,” declared another.
