Zipline Launches Medical Supply Drone Deliveries in Tanzania

WIRED 

Last month in Rwanda, a young woman started bleeding after giving birth by C-section. Try as they might, her doctors couldn't stop it. They'd already transfused the two units of matching blood that they had on-hand. They could have called the national blood bank in the capital of Kigali to request more, but ordering it, and sending it the 25 miles over mountainous roads to the hospital would take up to four hours. The woman didn't have that kind of time.
