High-Profile Searches

Air France Flight 447

Air France Flight 447 disappeared en route from Brazil to France on June 1, 2009.  Metron performed some initial analyses in 2009 to help find the aircraft, but by December 2010, the crash remained unlocated despite significant searches.  At this time Metron was asked to produce a probability map that incorporated the latest search efforts.  We also took into account the possibility that the black box beacons had failed – an unlikely but possible event.  When the physical search resumed in the spring of 2011, the plane was quickly found in a high probability area of detection.

US Coast Guard SAROPS

Metron helped to develop the United States Coast Guard’s Search and Rescue Optimal Planning System (SAROPS).  SAROPS is currently used by the Coast Guard for maritime search planning.  In 2013, the Coast Guard utilized SAROPS to locate John Aldridge, a lobsterman lost overboard off the coast of Long Island.

SS Central America

The SS Central America sank in 1857, taking to the ocean floor more than four tons of gold bars and coins.  In 1985, Metron was given the task of developing a probability map for the treasure hunt that was being conducted by Columbus America Discovery Group.  In 1986, a sonar search began which discovered the wreckage and the gold.  For more information, click here.

USS Scorpion

On May 22, 1968, the USS Scorpion, a nuclear submarine, was lost at sea.  She was on her way back from deployment in the Mediterranean heading to Naval Station Norfolk.  Dr. Lawrence D. Stone, currently Chief Scientist of Metron, assisted the US Navy in applying Bayesian search applications to this search.  The USS Scorpion was successfully located near the end of October 1968, she lay under more than 9,800 feet of water about 460 miles southwest of Azores.
