the researcher's note
Zipline drone delivery (Rwanda, Ghana). The measured health effect is real and large — a 2022 Lancet Global Health study on blood product delivery time and wastage, and reported reductions of 51-56% in deaths from postpartum haemorrhage at facilities served — but the decision procedure is engineered autonomy: flight control, routing and dispatch written by hand, not fitted to data. No source describes a learned component making the delivery decision. Fails gate 1 on the evidence available. If someone shows Zipline's demand-forecasting or inventory model is fitted and drives what is flown, this becomes an entry with a very strong effect number already waiting.
