Search: Searchers in the Southern Indian Ocean are preparing to launch a robotic submersible to look for wreckage from the missing Malaysia Flight 370. They’re hunting about 1,000 miles of the coast of Perth, Australia, where search ships last heard pings believed to have come from the jet’s black box. The submersible will be able to search the ocean floor for 16 hours at a time before coming to the surface and downloading data. Nothing has been heard since last Tuesday and the black box batteries are now thought to be dead five weeks into the search for the missing aircraft. The batteries are designed to last roughly 30 days.
