Rescues! (Paperback) (ISBN-13: 9781512433432)

A woman is buried in an avalanche. Miners are trapped underground. A sailor's boat capsizes in the ocean. A powerful tsunami sweeps people out to sea. Who will come to their rescue? And how will rescuers reach them? Author Sandra Markle captures the nail-biting action and shows how people use their brains, as well as their bravery, to rescue people in trouble all over the world. Rounding out the stories is the technology behind the emergencies and the rescues, including how the global positioning system works for locating victims, what the heart-lung machine does, and how robots and sensors can detect people buried in earthquakes or other disasters.
