A Drone Survival Guide with hints and tips on how to thwart the “robotic birds” has been published on the internet. With over 30,000 drones expected to be flying over the US by 2030, the Guide urges readers to familiarize themselves with the craft. In light of the growing number of drones, the Guide advises a number of techniques to evade and scramble drones. The document is available online and has been translated into 17 different languages. “Our ancestors could spot natural predators from far by their silhouettes. Are we equally aware of the predators in the present-day?” writes the Guide.
