A superhighway for drones to fly between British cities

Since they began to whirr and hover over a decade ago, small autonomous drones have turned from the plaything of hobbyists into the stuff of venture capitalists’ dreams. Drones now carry out many commercial tasks: inspecting infrastructure, surveying crops, filming videos, transporting medical supplies and, in some places, dropping off shopping and delivering pizzas. But such flights are strictly limited by aviation regulators in order to prevent accidents, especially collisions with manned aircraft. The British government has decided that it is time to give drones the freedom of the sky with the world’s biggest “superhighway”.
