Sub completes full search for Malaysia Airlines plane
A robotic submarine has completed its first full 16-hour mission scanning the floor of the Indian Ocean for wreckage of the missing Malaysian airliner after two previous missions were cut short by technical problems and deep water.
The Bluefin 21 covered 35 square miles of the silt-covered sea bed off the west Australian coast in its first three missions, the search co-ordination centre said.
