The drone economy could be grounded if operators and regulators alike don’t address pressing concerns over cyber attacks, privacy breaches and reckless pilots, according to a new report by insurers Lloyd’s of London. The British insurance giant’s risk report series survey, "Drones Take Flight," out Thursday, highlights five issues that could hamper the growth of businesses using unmanned aerial robots for jobs ranging from crop monitoring to parcel deliveries. Those factors, all which are critical to those insuring players in the drone economy, are crashes caused by poorly trained operators, drone hackers redirecting flights, a lack of an internationally agreed upon set of regulations, lax enforcement of said regulations, and privacy infringement.
