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.
In July 2009, Air France Flight 447 was lost in the middle of the Atlantic Ocean. An international SAR effort was launched, to no avail. A third effort nearly two years later discovered the crash site and recovered the black boxes.
In early 2014, Malaysia Airlines Flight 370 crashed under mysterious circumstances. Many nations contributed to the initial SAR effort, which was fruitless. In June 2014, the Australian Transport Safety Bureau commissioned the MV Fugro Equator to lead a three-month survey of the ocean bed, for which it had budgeted $60mn; at the same time, Malaysia announced it had spent $9.3mn to date on fuel and food in its own effort. The search for Flight 370 has become the largest SAR so far with the largest budget.
