Drones carry patients' blood for a fee in Rwanda
A drones start-up is launching a service that will deliver blood and plasma to hospitals in Rwanda.
Zipline will charge the government a per delivery fee for use of its fixed-wing aircraft.
The US firm says the amount is similar to what it costs to send packages by road, but it takes it much less time to make drop-offs.
The operation is thought to be the first commercial regular drone delivery service anywhere in the world.
