Boeing's prototype cargo drone can haul 500-pound loads

The rough-and-ready concoction of metal and batteries measures 15 feet long, 18 feet wide and 4 feet tall, weighing in at 747 pounds. In other words, it dwarfs the consumer DJI drone you got for Christmas. Obviously Boeing's prototype is far from a commercial product, but the firm says it'll be used "as a flying test bed to mature the building blocks of autonomous technology for future applications."
