Could ambulance drones appear on the battlefield?
Removing casualties from remote battlefields is often dangerous and highly skilled work for helicopter pilots.
But a prototype air ambulance drone developed by Tactical Robotics is hoping to make these evacuations safer.
Part funded by the Israel's Ministry of Defence, the AirMule, has a top speed of 120 knots (140 mph, 190 km/h) and can reach an altitude of 12,000 ft (3,600 m).
