One of the future beneficial uses of drones will surely be for beneficial purposes, such as "ambulance drones".
Alec Momont directs a project to design such "ambulance drones",
a project showing that the 100 mph speed with which drones
can reach a particular location unimpeded in a straight flight line
can greatly reduce the time required to bring needed equipment
to a critical medical situation.
