Missing jet likely in southern Indian Ocean

Investigators probing the disappearance of a Malaysia Airlines jetliner with 239 people on board believe it most likely flew into the southern Indian Ocean, a source close to the investigation said on Wednesday. An unprecedented search for the Boeing 777-200ER is under way involving 26 nations in two vast search "corridors", one arcing north overland from Laos towards the Caspian Sea, the other curving south across the Indian Ocean from west of Indonesia to west of Australia. "The working assumption is that it went south, and furthermore that it went to the southern end of that corridor," said the source. China said on Wednesday it had not yet found any sign of the aircraft crossing into its territory, according to Reuters.
