PERTH, Australia The head of the search effort says he believes searchers are closing in on the "final resting place" of Malaysia Airlines Flight 370.
This, after a navy ship heard more signals yesterday from deep in the Indian Ocean. And an analysis of two other sounds that were detected over the weekend showed they were consistent with a plane's flight recorders.
The signals are the strongest indication yet that the plane is now lying at the bottom of the ocean in the area where the search is focused.
Angus Houston, the Australian official who's coordinating the search, says he's "optimistic" that the plane will be found "in the not-too-distant future."
Yesterday marked one month since Flight 370 vanished on its way from Malaysia to Beijing with 239 people on board. The batteries that power the locator beacons for the flight recorders only last about a month.
If the batteries fail before they're found, locating them in such deep water would be difficult, if not impossible.
