Attack of the drones: sport's next big buzz

They have been responsible for innumerable deaths in the Middle East during the last decade and, if Amazon has its way, will deliver millions of toasters, gift sets and novels in the future. But recently drones have begun to fulfil a less utilitarian kind of role: competition in the nascent world of futuristic motorsports. A confluence of technological advances has made drone racing possible. A minuscule camera, mounted on the drone's nose, allows the pilot, as competitors are luxuriously titled, to control the vehicle through virtual reality-style goggles, as if perched in its tiny cockpit. With powerful lithium batteries, the size of which dictates the speed class of the drone, these machines, which are typically the size of a box of tissues, can reach speeds in excess of 120mph.
