The Navy’s U.S. Pacific Command is sending a black box locator to the Indian Ocean to aid in the search for Malaysian Airlines Flight 370, in the even debris from the plane is found.
The Towed Pinger Locator 25 system, used by the Navy to search for downed military and commercial aircraft, has highly sensitive listening capabilities and can detect pings from an aircraft’s black box — or flight data recorder — at depths up to about 20,000 feet.
