Cautious Optimism from the Indian Ocean in Search for Flight 370

PERTH, Australia (AP) — There's cautious optimism in the southern Indian Ocean today, where officials say more underwater signals have been detected.

The joint agency coordinating the search for Malaysia Airlines Flight 370 says sounds detected over the weekend, and on Tuesday, April 9, 2014, could be pings coming from the plane's two black boxes, but that still has to be confirmed.
