Search fails to pick up jet 'pings'

Search crews in the Indian Ocean have failed to pick up more of the faint underwater sounds that may have been from the missing Malaysian jetliner’s black boxes.

The signals first heard late on Saturday and early on Sunday had sparked hopes of a breakthrough in the search for Flight MH370, 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.
