California has a drone valley now. Zipline, a company already delivering blood and vaccines across Africa, is building a fleet of autonomous delivery drones in the U.S. that can drop a sandwich on your doorstep with dinner-plate accuracy. While Amazon talks and tests, Zipline’s aircraft have already logged 100 million commercial miles, quietly proving that sky deliveries aren’t hype — they’re here. In this episode, we head inside Zipline’s California test site and factory to see how these electric drones work, how they’re built, and why the company thinks it will beat Amazon to your backyard. We watch engineers launch aircraft, stress-test carbon-fiber wings, and demo a burrito-by-air drop that actually works. Enjoy!
