A drone developed by the German Fraunhofer Institute could be a great help to rescue teams. It is perhaps not an exaggeration to say that nothing shows better than the drone how much of a double-edged weapon technology can be. The flying device can be extremely fun to use in everyday life, and it’s also great for scientific purposes. But it can also be used to spy on others, or even as a weapon. No wonder the US military has recently developed a new weapon to disable drones.
