WFP's first use of humanitarian cargo drones in an emergency (Nepal floods, 2026, up to 100 kg per mission) reached about 9,000 people (https://www.wfp.org/stories/nepal-floods-where-roads-stop-humanitarian-cargo-drones-deliver); its Madagascar operation carried up to 160 kg per rotation (https://www.wfp.org/news/wfp-delivers-life-saving-nutrition-supplies-remote-communities-madagascar-unmanned-aircraft). The largest drone delivery network, Zipline, reported 2 million commercial deliveries in total by January 2026, mostly medical, not food at emergency scale (https://www.zipline.com/newsroom/zipline-surpasses-2-million-deliveries-raises-more-than-600m-to-power-next-phase-of-growth-and-expands-operations-to-houston-and-phoenix). Open source covers flight control (PX4, ArduPilot) without delivery or humanitarian mission logic (https://arxiv.org/pdf/2110.02260). Honest limit: cargo drones and airdrop are proven technologies; the open gap is cost per meal, payload and fleet operation at disaster scale, and tasks that only demonstrate a single drone drop are not new work.
