Subsurface Search for Black Box Under Way
Almost two dozen planes and ships trawled 135,000 square miles of ocean Friday trying to find the black box of missing Malaysia Airlines Flight 370.
The Australian navy ship Ocean Shield was towing a U.S.-supplied "pinger locator" that can scan beneath the surface for whatever faint signals the jet's battery-powered data recorder might still be sending almost a month after it disappeared with 239 people on board.
Australia's Joint Agency Coordination Center said one possible alert was picked up, but it was soon "discounted.""False alerts may be experienced from biological sources such as whales or interference from shipping noise," it said.
Eight other ships, 10 military planes and four civil jets were taking part in Friday's search, which covers essentially the same area that was searched Thursday, Australian Air Chief Marshal Angus Houston told reporters Friday.It's about 1,050 miles north of the western Australian port of Perth.
Conditions Friday were assessed as fair, with visibility of about 6 miles, the coordination center said.
