Ship hunts for more 'pings' in Malaysia jet search

PERTH, Australia (AP) - Search crews in the Indian Ocean failed to pick up more of the faint underwater sounds that may have been from the missing Malaysian jetliner's black boxes whose batteries are at the end of their life. The signals first heard late Saturday and early Sunday had sparked hopes of a breakthrough in the search for Flight 370, but Angus Houston, the retired Australian air chief marshal leading the search far off western Australia, said listening equipment on the Ocean Shield ship has picked up no trace of the sounds since then.
