A new drone wich is able to flyes and reach quickly patients, with an heart attack, was developed in Holland.
Called Ambulance Drone, it integrates a portable defibrillator.
This was the idea of the Belgian engineering graduate Alec Momont wich is behind of the project.
"The ambulance drone can get a defibrillator to a patient within a 12 square kilometre (4.6 square miles) zone within a minute, reducing the chance of survival from 8 percent to 80 percent."
This special drone can fly at speeds of up to 100 kilometres per hour (60 miles per hour), reaching a patient in matter of minutes where traffic congestion is an inescapable condition in all large and growing metropolitan areas across the world.
