Malaysia Airlines Missing Plane: Submarine Unable To Search For Jet Wreckage

The search area for the missing Malaysian jet has proved too deep for a robotic submarine which was hauled back to the surface of the Indian Ocean less than half way through its first seabed hunt for wreckage and the all-important black boxes, authorities said on Tuesday.

Search crews sent the Bluefin 21 deep into the Indian Ocean on Monday to begin scouring the seabed for the missing Malaysia Airlines Boeing 777 after failing for six days to detect any signals believed to be from its black boxes.

But after only six hours of its planned 16-hour mission on the sea bed, the autonomous underwater vehicle exceeded its maximum depth limit of 4,500 meters (15,000 feet) and its built-in safety feature returned it to the surface, the search coordination center said in a statement on Tuesday.

What if anything it might have discovered during the six-hour search was still being analyzed, the center said.

The Bluefin 21 will resume the search Tuesday when weather conditions permit, it said.

Search authorities knew that the primary wreckage from Flight MH370 was likely lying at the limit of the Bluefin's dive capabilities. Deeper diving submersibles have been evaluated, but none is yet available in the search area.
