Robot sub to extend search area for missing planeBy AP News Apr 27, 2014 10:57AM UTC
CANBERRA, Australia (AP) — Authorities say a robotic submarine scanning the Indian Ocean floor for the missing Malaysia Airlines jet is expected to complete its search of the most likely crash site. With no clue yet found of the missing Boeing 777, the search area will then be extended.
The U.S. Navy’s Bluefin 21 has been creating a three-dimensional sonar map of the ocean floor near where signals consistent with airplane black boxes were heard on April 8.
The search area is a circle with a 10-kilometer (6-mile) radius, 4.5 kilometers (2.8 miles) deep off the Australian coast.
The search coordination center says in a statement the Bluefin 21 is expected to complete the focused underwater search area and continue examining adjacent areas during a mission starting Sunday.
