This is all pointless until the FAA or Congress relax that BVLOS regulations. Same with Walmart and DroneUp.
Once the way is clear, this will become more popular.
I'll be in D.C. on Wednesday next week talking with Congress folks about this very thing. We also have our BVLOS Task Group report due to be presented to the FAA at the AAAC meeting next month.
I'll post a link to that meeting once it's announced.
Will delivery drones every darken the sky (as both extreme opponents and proponents claim)? No. But once it's commonplace, we'll see more of them being used for many aspects of delivery. Mostly last mile, but some local deliveries as well.
But nothing can happen until the FAA gets out of our way. And quickly! There are some drone delivery companies burning through capital too fast, and they'll run out before they can start making money. It's the FAA's fault.
