Amazon’s drone delivery program stopped being a joke a while ago, but the company still has to overcome serious challenges to make the technology actually work. One of these is getting drones near enough to large populations so they’re more efficient than regular road delivery. Amazon has an idea for that though: Huge. Drone. Beehives.
The article goes on to question whether this is possible because of the risks of noise, congestion, and crashes. (Seems like we’ve lived with that stuff with cars for a long time now.)
