Via The Economist:
America’s aviation regulators have been asked by Congress to integrate unmanned aircraft into the air-traffic control system as early as 2015…Pilotless aircraft could carry out many jobs at a lower cost than manned aircraft and helicopters—tasks such as traffic monitoring, border patrols, police surveillance and checking power lines. They could also operate in conditions that are dangerous for pilots, including monitoring forest fires or nuclear-power accidents. And they could fly extended missions for search and rescue, environmental monitoring or even provide temporary airborne Wi-Fi and mobile-phone services. Some analysts think the global civilian market for unmanned aircraft and services could be worth more than $50 billion by 2020.
