"Bezos is proposing to build a fleet of small robotic eight-motored helicopters – drones – to carry individual packages under five pounds in weight within a 10 mile radius of delivery centers," notes Drew Reed.
"Are we witnessing the dawn of a brave new dronecopter world? No one is certain, but Bezos’s vision is certainly a lot more plausible than the tacocopter and may yet see the light of day. And who knows? Perhaps upping the number of drone deliveries isn’t a bad thing (provided the drones aren’t equipped with weapons like their wartime counterparts). It means fewer trucks on the street, though how much fewer is unclear; it’s going to take a whole lot of five-pound drone shipments to equal the weight carried by just one two-ton truck."
