Drone delivery is about to be cheaper than cars. But the drone is only 15% of the work to get there. A decade after starting in Rwanda flying blood to one hospital, @zipline has flown 140M+ autonomous miles with zero safety incidents, expanded to the US and to food delivery and household items, and delivery costs have fallen from $300 to $12 - now cheaper than a car. Getting there meant building almost everything from scratch: flight computers, motors, GPS modules, even the air traffic software regulators use to track them. And it meant a discipline most engineers find nearly impossible. That's the reality behind Zipline, the largest autonomous system on Earth. @Keller and @EricWattage joined me and @gradypb to talk more about their journey. 00:00 Introduction 02:28 Early Vision and Regulation 04:09 Rwanda Launch Hard Lessons 06:49 Scaling to 24/7 Impact 09:35 Real World Ops Surprises 11:15 Safety Redundancy Failover 20:24 Precision Delivery Pod Tech 25:34 Building the Drone Network 26:51 Fleet Commanders Explained 28:22 Scaling to a Million a Day 29:51 Autonomy Enables 24 7 Ops 31:52 Reinventing Air Traffic Control 36:08 Why Zipline Is Vertical 41:40 First Principles Delete Parts 44:45 Market Explosion and Closing Thoughts
