The British government is working with the online retail giant Amazon to begin the testing of drone delivery services in the country. Although Amazon is paying for the testing to take place, ministers have said that they wish to create an environment where delivery drones can be used safely beyond 2020. The programme will primarily look into the safety of the robotic aircraft, particularly when in flight and beyond the 'line of sight'. Amazon says that the programme has been set up in the United Kingdom due to the more relaxed aviation rules there, which mean that more realistic testing can take place. It hopes that if the testing succeeds, it will be able to make delivery times of around half an hour a possibility, using drones capable of flying at around 50mph, up to 10 miles from a base location.
