The technology used in search-and-rescue at sea was developed by NASA. Learn more about cool NASA innovations in this interactive animation from Discovery Channel.

Every time a hiker is lost in the woods, the local news stations will no doubt show images of helicopters buzzing overhead, German Shepherds sniffing the forest floor and scores of people combing the woods in search of clues. This brief bit of insight into the world of search and rescue (SAR) teams is about all the general public ever sees. In reality, SAR goes way beyond these glimpses on the news -- it's an extensive emergency service performed by highly trained military specialists, local law enforcement and civilian volunteers.

The goal of SAR is to locate, stabilize and extract individuals in distress. That can mean a hiker on the side of a mountain, a sailor lost at sea, a trapped urban disaster survivor, a captured soldier or an Alzheimer's patient wandering city streets. Each area of SAR employs techniques specific to the circumstance. Air and sea rescue requires skilled ocean swimmers and helicopter pilots. Combat rescue uses the military's most accomplished Special Forces teams. Urban SAR requires hazardous material experts and structural specialists.

Predator Drones
In May 2006, the Federal Aviation Administration (FAA) authorized the use of the unmanned MQ-1 and MQ-9 Predator planes to be used for civilian SAR. These remote-controlled planes are equipped with infrared cameras that can spot a heat source as small as a human from 10,000 feet. The use of the Predator, while limited at the moment because of the war in Iraq, could mean saving the lives of many natural disaster victims in the future [source: USAF].

From FEMA to county­ sheriff departments, expert technicians to local volunteers -- SAR teams do important work all over the world every day. In this article, we'll look at the different training SAR­ teams undergo to perform their duties as well as the vehicles and equipment they use. We'll also highlight specific areas of SAR and learn about the methods and techniques they use to safely locate and extract people in need.
