Amazon doesn't need this to use drones for 100% of deliveries. But if they pick enough constraints, could it work? Assume it will never work in NYC, but could it work in Albuquerque, New Mexico? Assume it won't fly if the winds are over mph. Assume that only human operated landings are performed the first time to scope the landing zone, with future approach and landings to be automated. Assume that anything unexpected causes the delivery to get canceled. In the 60 Minutes interview, Bezos was optimistic but more cautious about when it would be ready -- more like 2018+. Also, the earlier part of the segment was about how it took Amazon Fresh 5 years to expand grocery delivery to its second city. Bezos, of all tech companies, knows the value of staying with a problem for the long term. If I had to bet if Amazon could figure this out over the next 50 years, I would say yes. Sooner is a bonus.
