Unmanned military aircraft have tracked and killed terrorists in the Middle East and Asia. Their civilian cousins are now in demand by police departments, border patrols, power companies, news organizations and others wanting a bird’s-eye view that’s too impractical or dangerous for conventional planes or helicopters to get.
Along with the enthusiasm, there are qualms.
Drones overhead could invade people’s privacy. The government worries they could collide with passenger planes or come crashing down to the ground.
