Alibaba begins drone delivery trials
China's biggest internet retailer says it has begun testing drone-based deliveries to hundreds of customers. It says the trial will last three days and be limited to areas within a one-hour flight of its distribution centres in Beijing, Shanghai and Guangzhou. The company's blog adds that it believes the technology has the potential to speed up deliveries. Amazon, Google and parcel service UPS are among other companies carrying out more private trials of such aircraft.
