What Zipline have accomplished here is incredible – I’ve been stunned by the 5-minute order-to-takeoff response time, the 80km range, and the amount of safety and resilience built into the drones.
Even technologically, they’ve made some amazing improvements – their most recent revision of the recapture system reduced the capture target on the drone from about 3 feet to about a centimetre, and their drop target at the hospitals is as small as two car parking spaces. In some of the videos you can see a hospital has a patch of grass which is fairly worn with all the deliveries – which makes me think they’re accurately dropped by parachute to within a 50cm.
