Drones deliver blood and medical supplies in Rwanda

Doctors in rural Rwanda are able to order blood and medical supplies by text message and then have them delivered by a drone.

Technology company Zipline has developed a system where drones are catapulted by zip wire into the air. The drones then travel at 80mph, releasing their delivery when they reach their destination.
