FedEx will start testing a 1,900-pound drone for hauling packages

Consider the idea of a package delivered by drone, and it’s easy to imagine a small flying machine depositing an item in a consumer’s driveway or backyard. And indeed, that’s what companies such as Wing, from Google’s parent Alphabet, are working on right now. But FedEx, which announced last week that it’s teaming up with a drone company called Elroy Air, has something else in store: an exploration of how to use drones for what they call “middle mile” logistics.
