Mini-sub search could end within a week

The current underwater search for missing Malaysia Airlines Flight MH370, focused on a tight 10 km circle of the sea floor, could be completed within a week, Australian search officials said yesterday.
Malaysia said the search was at a "very critical juncture" and asked for prayers for its success. A US Navy deep-sea autonomous underwater vehicle is scouring a remote stretch of the Indian Ocean floor for signs of the plane, which disappeared from radars on March 8 with 239 people on board.
After almost two months without a sign of wreckage, the current underwater search has been narrowed to a small area around the location in which one of four acoustic signals believed to be from the plane's black box recorders was detected on April 8, officials said.
Officials did not indicate whether they were confident that this search area would yield any new information, nor did they state what they would do if  the underwater search were to prove fruitless.
