That is certainly an interesting point. Modern distribution centers use conveyers to move packages to the truck loading port where they will be loaded on to trucks for delivery. Why not extend the conveyer through the sky to a truck loading port a couple of miles away. If you lay out reliable ingress&#x2F;egress channels for the drone traffic you could probably stack 300 - 400 drones per mile in that channel, operating all day would certainly expand the virtual &quot;size&quot; of your warehouse.
