Silicon Valley drone company, Zipline has teamed up with the Rwandan health ministry to deliver blood and other urgently needed medical supplies to hospitals around the country much faster than before. Blood deliveries by drone have reduced the time it takes to get blood to where it is needed, from four hours on average to half an hour. The Zipline delivery drones can fly up to 65 mph and have a 47-mile service radius. Over the last year, the drones have completed over 5,500 units of blood, often in life-saving situations to 12 regional hospitals. The use of unmanned aerial vehicles has helped to reduce maternal deaths, a quarter of which are the result of blood loss during childbirth.
