Three Ships Report Undersea Pings

On Saturday, a Chinese vessel searching for the Boeing 777 that went down in the Indian Ocean in March detected a pulse that could be coming from the plane's "black box." Now two more ships, another Chinese ship and an Australian one, have also reported pings. One was about a mile away from the first pulse, and the third was in a different location. Searchers are taking the "acoustic events" very seriously, the said, and are hoping to find the plane's black box before its batteries expire any day now.
