Search and rescue

Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water.

International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations. The duty to render assistance is covered by Article 98 of the UNCLOS.

There are many different definitions of search and rescue, depending on the agency involved.

One of the world's earliest well-documented SAR efforts ensued following the 1656 wreck of the Dutch merchant ship Vergulde Draeck off the west coast of Australia. Survivors sought help, and in response three separate SAR missions were conducted, without success.

On 29 November 1945, a Sikorsky R-5 performed the first civilian helicopter rescue operation in history, with Sikorsky's chief pilot Dmitry "Jimmy" Viner in the cockpit, using an experimental hoist developed jointly by Sikorsky and Breeze. All 5 crew members of an oil barge, which had run aground on Penfield Reef, were saved before the barge sank.

In 1983, Korean Air Lines Flight 007 with 269 occupants was shot down by a Soviet aircraft near Sakhalin. The Soviets sent SAR helicopters and boats to Soviet waters, while a search and rescue operation was initiated by U.S., South Korean, and Japanese ships and aircraft in international waters, but no survivors were found.
